How to calculate time in Excel - time difference, adding / subtracting times

This tutorial focuses on various ways to calculate times in Excel. You will find a few useful formulas to add and subtract times, calculate time difference, or elapsed time, and more.

In the last week's article, we had a close look at the specificities of Excel time format and capabilities of basic time functions. Today, we are going to dive deeper into Excel time calculations and you will learn a few more formulas to efficiently manipulate times in your worksheets.

How to calculate time difference in Excel (elapsed time)

To begin with, let's see how you can quickly calculate elapsed time in Excel, i.e. find the difference between a beginning time and an ending time. And as is often the case, there is more than one formula to perform time calculations. Which one to choose depends on your dataset and exactly what result you are trying to achieve. So, let's run through all methods, one at a time.

Formula 1. Subtract one time from the other

As you probably know, times in Excel are usual decimal numbers formatted to look like times. And because they are numbers, you can add and subtract times just as any other numerical values.

The simplest and most obvious Excel formula to calculate time difference is this:

=End time - Start time

Depending on you data structure, the actual time difference formula may take various shapes, for example:

Formula Explanation
=A2-B2 Calculates the difference between the time values in cells A2 and B2.
=TIMEVALUE("8:30 PM") - TIMEVALUE("6:40 AM") Calculates the difference between the specified times.
=TIME(HOUR(A2), MINUTE(A2), SECOND(A2)) - TIME(HOUR(B2), MINUTE(B2), SECOND(B2)) Calculates the time difference between values in cells A2 and B2 ignoring the date difference, when the cells contain both the date and time values.

Remembering that in the internal Excel system, times are represented by fractional parts of decimal numbers, you are likely to get the results similar to this:
Calculating time difference in Excel

The decimals in column D are perfectly true but not very meaningful. To make them more informative, you can apply custom time formatting with one of the following codes:

Time code Explanation
h Elapsed hours, display as 4.
h:mm Elapsed hours and minutes, display as 4:10.
h:mm:ss Elapsed hours, minutes and seconds, display as 4:10:20.

To apply the custom time format, click Ctrl + 1 to open the Format Cells dialog, select Custom from the Category list and type the time codes in the Type box. Please see Creating a custom time format in Excel for the detailed steps.

And now, let's see how our time difference formula and time codes work in real worksheets. With Start times residing in column A and End times in column B, you can copy the following formula in columns C though E:

=$B2-$A2

The elapsed time is displayed differently depending on the time format applied to the column:
The elapsed time is displayed differently depending on the applied time format.

Note. If the elapsed time is displayed as hash marks (#####), then either a cell with the formula is not wide enough to fit the time or the result of your time calculations is a negative value.

Formula 2. Calculating time difference with the TEXT function

Another simple technique to calculate the duration between two times in Excel is using the TEXT function:

  • Calculate hours between two times: =TEXT(B2-A2, "h")
  • Return hours and minutes between 2 times: =TEXT(B2-A2, "h:mm")
  • Return hours, minutes and seconds between 2 times: =TEXT(B2-A2, "h:mm:ss")

Calculating time difference with TEXT function

Notes:

  • The value returned by the TEXT function is always text. Please notice the left alignment of text values in columns C:E in the screenshot above. In certain scenarios, this might be a significant limitation because you won't be able to use the returned "text times" in other calculations.
  • If the result is a negative number, the TEXT formula returns the #VALUE! error.

Formula 3. Count hours, minutes or seconds between two times

To get the time difference in a single time unit (hours ,minutes or seconds), you can perform the following calculations.

Calculate hours between two times:

To present the difference between two times as a decimal number, use this formula:

=(End time - Start time) * 24

Supposing that your start time is in A2 and end time in B2, you can use a simple equation B2-A2 to calculate the difference between two times, and then multiply it by 24, which is the number of hours in one day:

=(B2-A2) * 24

To get the number of complete hours, use the INT function to round the result down to the nearest integer:

=INT((B2-A2) * 24)
Calculating hours between two times in Excel

Total minutes between two times:

To calculate the minutes between two times, multiply the time difference by 1440, which is the number of minutes in one day (24 hours * 60 minutes = 1440).

=(End time - Start time) * 1440

As demonstrated in the following screenshot, the formula can return both positive and negative values, the latter occur when the end time is less than the start time, like in row 5:

=(B2-A2)*1440
Calculating total minutes between two times in Excel

Total seconds between times:

To get the total seconds between two times, you multiply the time difference by 86400, which is the number of seconds in one day (24 hours * 60 minutes * 60 seconds = 86400).

=(End time - Start time) * 86400

In our example, the formula is as follows:

=(B2-A2)* 86400
Calculating total seconds between two times

Note. For the results to display correctly, the General format should be applied to the cells with your time difference formula.

Formula 4. Calculate difference in one time unit ignoring others

To find the difference between 2 times in a certain time unit, ignoring the others, use one of the following functions.

  • Difference in hours, ignoring minutes and seconds:

    =HOUR(B2-A2)

  • Difference in minutes, ignoring hours and seconds:

    =MINUTE(B2-A2)

  • Difference in seconds, ignoring hours and minutes:

    =SECOND(B2-A2)

When using Excel's HOUR, MINUTE and SECOND functions, please remember that the result cannot exceed 24 for hours and 60 for minutes and seconds.
Calculate time difference in one unit ignoring others

Note. If the end time is less than the start time (i.e. the result of the formula is a negative number), the #NUM! error is returned.

Formula 5. Calculate elapsed time from a start time to now

In order to calculate how much time has elapsed since the start time to now, you simply use the NOW function to return today's date and the current time, and then subtract the start date and time from it.

Supposing that the beginning date and time is in call A2, the formula =NOW()-A2 returns the following results, provided you've applied an appropriate time format to column B, h:mm in this example:
Calculating elapsed time from a start time to now

In case the elapsed time exceeds 24 hours, use one of these time formats, for example d "days" h:mm:ss like in the following screenshot:
Calculating elapsed time over 24 hours

If your starting points contain only time values without dates, you need to use the TIME function to calculate the elapsed time correctly. For example, the following formula returns the time elapsed since the time value in cell A2 up to now:

=TIME(HOUR(NOW()), MINUTE(NOW()), SECOND(NOW())) - A2
Calculating elapsed time without dates

Note. The elapsed time is not updated in real-time, it refreshes only when the workbook is reopened or recalculated. To force the formula to update, press either Shift + F9 to recalculate the active spreadsheet or hit F9 to recalculate all open workbooks.

Formula 5. Display time difference as "XX days, XX hours, XX minutes and XX seconds"

This is probably the most user-friendly formula to calculate time difference in Excel. You use the HOUR, MINUTE and SECOND functions to return corresponding time units and the INT function to compute the difference in days. And then, you concatenate all these functions in a single formula along with the text labels:

=INT(B2-A2) & " days, " & HOUR(B2-A2) & " hours, " & MINUTE(B2-A2) & " minutes and " & SECOND(B2-A2) & " seconds"
A user-friendly Excel time difference formula

To instruct your Excel time difference formula to hide zero values, embed four IF functions into it:

=IF(INT(B2-A2)>0, INT(B2-A2) & " days, ","") & IF(HOUR(B2-A2)>0, HOUR(B2-A2) & " hours, ","") & IF(MINUTE(B2-A2)>0, MINUTE(B2-A2) & " minutes and ","") & IF(SECOND(B2-A2)>0, SECOND(B2-A2) & " seconds","")

The syntax may seem excessively complicated, but it works :)

Excel time difference formula that ignores zero values

Alternatively, you can calculate time difference by simply subtracting the start time from the end time (e.g. =B2-A2), and then apply the following time format to the cell:

d "days," h "hours," m "minutes and" s "seconds"
Subtract the start time from the end time and apply the custom time format to the cell.

An advantage of this approach is that your result would be a normal time value that you could use in other time calculations, while the result of the complex formula discussed above is a text value. A drawback is that the custom time format cannot distinguish between zero and non-zero values and ignore the latter. To display the result in other formats, please see Custom formats for time intervals over 24 hours.

How to calculate and display negative times in Excel

When calculating the time difference in Excel, you may sometimes get the result as ###### error because the difference is a negative time. But is there a way to show negative times properly in Excel? Of course, there is a way, and even more than one :)

Method 1. Change Excel Date System to 1904 date system

The fastest and easiest way to display negative time normally (with a minus sign) is switching to the 1904 date system. To do this, click File > Options > Advanced, scroll down to the When calculating this workbook section and put a tick in the Use 1904 date system box.
Changing to the 1904 data system

Click OK to save the new settings, and from now on negative times will be displayed correctly, like negative numbers:
In the 1904 date system, negative times are displayed like negative numbers

Method 2. Calculate negative time in Excel with formulas

Is changing Excel's default Date System is not an option, then you can force negative times to display properly using one of the following formulas:

=IF(A2-B2>0, A2-B2, "-" & TEXT(ABS(A2-B2),"h:mm"))

=IF(A2-B2>0, A2-B2, TEXT(ABS(A2-B2),"-h:mm"))

Both formulas check if the time difference (A2-B2) is greater than 0, and if it is they return that difference. If the time difference is less than zero, the first formula calculates the absolute difference and concatenates the minus sign. The second formula yields exactly the same result by using a negative time format "-h::mm".
A formula to calculate negative times in Excel

Note. Please keep in mind that unlike the first method that treats negative times as negative numeric values, the result of the TEXT function is always a text string that cannot be used in calculations or other formulas.

Adding and subtracting time in Excel

Basically, there are 2 ways to add and subtract time in Excel:

  • Using the TIME function
  • Using arithmetic calculations based on the number of hours (24), minutes (1440) and seconds (86400) in one day

The TIME(hour, minute, second) function makes Excel time calculations really easy, however it does not allow adding or subtracting more than 23 hours, or 59 minutes, or 59 seconds. If you are working with bigger time intervals, then use one of the arithmetic calculations demonstrated below.

How to add or subtract hours to time in Excel

To add hours to a given time in Excel, you can use one the following formulas.

TIME function to add under 24 hours

=Start time + TIME(N hours, 0, 0)

For example, if your start time is in cell A2, and you want to add 2 hours to it, the formula is as follows:

=A2 + TIME(2, 0, 0)
TIME function to add under 24 hours

Note. If you try adding more than 23 hours with the TIME function, the specified hours will be divided by 24 and the remainder will be added to the start time value. For example, if you try to add 25 hours to "6/2/2015 10:00 AM" (cell A4) using the formula =A4 + TIME(25, 0, 0), the result will be "06/02/2015 11:00", i.e. A4 + 1 hour.

Formula to add any number of hours (under or over 24 hours)

The following formula has no limitations to the number of hours you want to add:

= Start time + (N hours / 24)

For example, to add 28 hours to the start time in cell A2, enter the following formula:

=A2 + (28/24)

Universal formula to add hours to a given time in Excel

To subtract hours from a given time, you use analogous formulas, and just replace "+" with the minus sign:

For example, to subtract 3 hours from the time in cell A2, either of the following formulas will do:

=A2-(3/24)

=A2-TIME(3,0,0)

To subtract more than 23 hours, use the first one.

How to add / subtract minutes to time in Excel

To add minutes to a given time, employ the same techniques that we've just used for adding hours.

To add or subtract under 60 minutes

Use the TIME function and supply the minutes you want to add or subtract in the second argument:

=Start time + TIME(0, N minutes, 0)

And here are a couple of real-life formulas to calculate minutes in Excel:

To add 20 minutes to the time in A2: =A2 + TIME(0,20,0)

To subtract 30 minutes from the time in A2: =A2 - TIME(0,30,0)

To add or subtract over 60 minutes

In your calculation, divide the number of minutes by 1440, which is the number of minutes in a day, and add the quotient to the start time:

=Start time + (N minutes / 1440)

To subtract minutes from time, simply replace plus with the minus sign. For example:

To add 200 minutes: =A2 + (200/1440)

To subtract 300 minutes: =A2 -(300/1440)

Adding and subtracting minutes in Excel

How to add / subtract seconds to a given time

Second calculations in Excel are done in a similar fashion.

To add under 60 seconds to a given time, you can use the TIME function:

=Start time + TIME(0, 0, N seconds)

To add more than 59 seconds, use the following formula:

=Start time + (N seconds / 86400)

To subtract seconds, utilize the same formulas with the minus sign (-) instead of plus (+).

In your Excel worksheets, the formulas may look similar to these:

To add 30 seconds to A2: =A2 + TIME(0,0,31)

To add 1200 seconds to A2: =A2 + (1200/86400)

To subtract 40 seconds from A2: =A2 - TIME(0,0,40)

To subtract 900 seconds from A2: =A2 - (900/86400)

How to sum time in Excel

The Excel sum time formula is the usual SUM function, and applying the proper time format to the result is what does the trick.

Supposing you have a few project times in column B and you want to add them up. You write a simple SUM formula like =SUM(B2:B4) and get the result in the default format, like hh:mm:ss.
A SUM formula to add up times in Excel

In some cases the default time format works just fine, but sometimes you may want more, for example to display the total time as minutes and seconds, or seconds only. The good news is that no other calculations are required, all you have to do is apply custom time format to the cell with the SUM formula.

Right click the cell and select Format Cells in the context menu, or press Ctrl + 1 to open the Format Cells dialog box. Select Custom from the Category list and type one of the following time formats in the Type box:

  • To display total time as minutes and seconds: [m]:ss
  • To display total time as seconds: [ss]

The result will look as follows:
Apply the custom time format to display total time as minutes and seconds, or seconds only.

How to sum over 24 hours in Excel

In order to add up more than 24 hours, you use the same SUM formula as discussed above, and apply one of the following time formats to the cell:

Format Displays as Explanation
[h]:mm 30:10 Hours and minutes
[h]:mm:ss 30:10:20 Hours, minutes and seconds
[h] "hours", mm "minutes", ss "seconds" 30 hours, 10 minutes, 20 seconds
d h:mm:ss 1 06:10:20 Days, hours, minutes and seconds
d "day" h:mm:ss 1 day 06:10:20
d "day," h "hours," m "minutes and" s "seconds" 1 day, 6 hours, 10 minutes and 20 seconds

To see how these custom time formats may look like in your Excel worksheet, please have a look at the screenshot below, where the same SUM formula is entered in cells A9 to A13:

=SUM($B$2:$B$4)

Adding up more than 24 hours in Excel

Note. The above custom time formats work for positive values only. If the result of your time calculations is a negative number, e.g. when you are subtracting a bigger time from a smaller time, the result will be displayed as #####. To display negative times differently, please see custom format for negative time values.

Also, please keep in mind that the time format applied to a cell changes only the display presentation without changing the cell's value. For example, in the screenshot above, cell A13 looks like text, but in fact it's a usual time value, which is stored as a decimal in the internal Excel system. Meaning, you are free to refer to that cell in other formulas and calculations.

    I need to make a cell (minutes late) using 1 cell (Scheduled departure time) being subtracted from another cell (actual departure time). The trick is i need the time starting at 12:00 pm. Ex: Truck leaves at 12:15 am, but the Scheduled time is 11:45 pm. My current sheet shows 23:30 minutes late instead of 30 mins.

  2. Sach says:

    (Stop time) - (Start time) = (IF =0, then add one minute to stop time);
    (08:00.50) - (08:00.10) = 0 (error)
    Thus, 08:01 -08:00.10 = 1 (acceptable)

    Need to perform a calculation on an employee schedule (utilizing the 24 hour clock) where start time is 19:00 (A11) and end time is 03:00 (A12) and get an answer that is not in negative hours ( =SUM(A12-A11) currently returns -16). When I use the hours 16:30 (B11) and 23:30 (B12) that do not span midnight (2400) then the calculations are correct ( =SUM(B12-B11) currently returns 7:30), which I can easily convert to 7.5 hours, any suggestions without having to program the dates into the start times?

    • Will says:

      Hi Woody,
      just add 24 hours if the time will be negative :
      =IF(A12<A11,A12-A11+24,A12-A11)
      expl : check if value A12 is less then A11; if so add 24 to the difference, else just use the difference.
      Think it will work for you.

  12. Brenda says:

    Using the 12 hour format, I am struggling to calculate the duration of hours when the start time begins at PM and the out time ends at AM. For example, if I wanted to find the duration of hours from 12:30AM(A1) to 3PM(A2), I would use the formula =(A2-A1)*24, which is 14.5 hours. BUT this does not work if I were to calculate the duration from 3PM(A1) to 12:30AM(A2), which is 9.5 hours but formula =(A2-A1)*24 will give me -14.5. What formula would I use to find the difference of time from PM to AM?

    • Hello Brenda,
      Here is the formula to solve your task:

      =(IF(A2 > A1, A1+1, A1)-A2)*24

    • Tiffany.S says:

      You can use the formula =(IF([@Start],[@End],[@End])-[@Start]) and write the end time as over the 24 mark rather than going back to 00:00:00. For example: start= 23:00:00, end= 25:00:00, and the duration it gives you will be 02:00:00.

      The formula provided by Mary also works! If you want the same formula for the whole collumn though, that's what I use.

    Thank you so much!

    • Pablo says:

      Is the end time always on the same day as the start time?
      Total Hours = (End time - Start time) * 24
      For example -> C1 = (B1-A1)*24
      Where:
      A1 = Start time
      B1 = End time
      C1 = Total Hours
      Make sure the number format for the total hours cell is general or number.

  20. Agnes says:

    Hi, I'd like to count elapsed time but in the situation when dates and hours are in separate cells.
    A1=Start B1=2019-01-12 C1=6:00
    A2=End B2=2019-15-12 C2=20:40
    I'd like the result to be divided into full days (24h) and the remaining time.

    i given one small example for this comment box
    K Column 8:30 to L Column 10:00 =IF(K3>L3,1+L3,L3)-K3
    M Column Result is 1:30
    But in the Same M Column I need time difference in Minute in the same Cell like 90 minute

    • Phil Lawrence says:

      Change your formula to =(IF(K3>L3,1+L3,L3)-K3)x1440 and you will get your answer in minutes.

      1440 being the number of minutes in a day.

  24. Cindy says:

    I have start time and total hours worked for the day. How can I get the end time?

    • Hello Cindy,

      To find out the exact end time, just use the formula below:

      =A1+TIME(B1, 0, 0)

      Where A1 is the start time and B1 is the total hours to work.

  25. Beth says:

    I have a schedule with start times and finish times.
    I made separate column for how many hours each day.
    How do I add these times up to find how many hours per week?
    From there I will need to make a separate sheet to calculate hours over 80 per pay period.
    I thought it would be something like this:
    =TEXT(R5:X5, "h:mm") but it isn't working

    • Phil Lawrence says:

      Hi Beth
      you have made your result to be TEXT and you cannot calculate with text.
      Also when a result is more than 24 hours you have to be careful with formats otherwise Excel will not display what you are expecting. Use cell format "General" or "Number" but not time. If you use time everything goes back to zero after 23:59 like a clock.
      Apart from that, then calculate as normal =sum(R5:X5) or if you really want to =Sum(R5:X5,"[h]:mm") The bracket around the h tells excel to go beyond the 24 hour constraint it normally uses and you need that. Make sure R5 through to X5 are numbers not text as well and watch those formats, it can mess up your calculations big time.

  27. Amos says:

    I have a formula to calculate time in excel, which works good, but if I clock in at say 6:30 AM, (cell, C3) it shows a total time, even if the other cells are empty. Is there a way to not calculate time until more then one cell is populated? It is to clock in and out, AM and PM. The formula is,
    =((IF(C3>D3,D3+1,D3)-C3)*24)+(IF(E3>F3,F3+1,F3)-E3)*24
    Can someone please help me with this, or is there a better way of doing it? Thanks!

    • Phil Lawrence says:

      Just add some more nests to your formula to check if D3 and F3 are empty.
      =If(D3="","") will check D3 and if it is blank will make the cell with the formula in it blank as well. Build this check into your existing formula and you will get what you are after.

    Thank you.

  29. Amos says:

    Ok, Thanks for your response, however I was not able figure out where to put that, should I put it in the very beginning? I just couldn't get it to work.I have IN, OUT, IN, Out, and if I put in say 6:30 for the first in without any of the others populated, the total time says 17.25 Hours, and I would like it to say 0 until I enter a out time. Thanks a lot for helping!

    • Hello Amos!
      Please use the formula below:
      =IF(COUNTA(C3:F3)>1, ((IF(C3>D3, D3+1, D3)-C3)*24)+(IF(E3>F3, F3+1, F3)-E3)*24, "")

        Hi Alexander, Thanks so much for the formula that you posted, and it works great for when I enter the IN time in the morning, but when I enter the IN time after lunch it shows the 16.5 hours again. I suppose I just need to add something? I am lost when it comes to these long formulas. So I have IN, OUT, IN, OUT I enter the time to the closest 15 minutes, then the total column shows the hours. Please let me know if you have any thoughts to get the time to show only the hours in the forenoon if I enter the IN time in the afternoon. Thanks!

        • Hello!
          Check what values you enter in C3 D3 E3 and F3. If only one value is filled, the formula does not count time. Give an example of the source data and the expected result.
          It’ll help me understand it better and find a solution for you. Thank you.

        • Amos says:

          Ok, so what I would like is if G3 (which is the total hours) does not show a total unless D3 or F3 is populated. Currently I have this formula in G3.
          =IF(COUNTA(C3:F3)>1, ((IF(C3>D3, D3+1, D3)-C3)*24)+(IF(E3>F3, F3+1, F3)-E3)*24, "")
          Currently it shows 17 Hours if I have a time in E3 but not F3. It seems like C3 and D3 are working exactly how I want them. Thanks a lot! Amos

  30. Amber Fryer says:

    I am needing a formula that subtracts hours worked from 40. I am needing to know the left over hours. Basically I need it to subtract worked hours for the week let’s say 25.50 from 40 hours allowed for the week and give me the sum of that. So 40 - 25.5 =14.50

    • Hello Amber!
      If you enter working hours in the hh:mm:ss format, you can find the sum with the help of ordinary addition. Suppose you type the time in cells B2:B7 and get the sum in cell B8. However, when you sum several time intervals, the result can turn out to be over 24 hours. In this case, Excel resets the sum to zero and starts the operation anew. To show the correct sum of working hours, please apply a special format to B8: open the Format Cells dialog window, go to Number -> Time and choose "37:30:55" from the Type list. Then enter 40:00:00 which is your maximum working time in a separate cell, e.g. C1. After that, change the formula in cell B8 to see the left-over hours:

      =IF(C1 < SUM(B2:B7), "Over 40 hours on "&TEXT((SUM(B2:E7)-C1), "hh:mm"), C1-SUM(B2:B7))

    How can I convert times to decimals in military time? I'm trying to write a sheet where I input time in and time out using 4 digit military time (6 AM as 0600, 2 PM as 1400), and receive total hours worked. For example, I have time in as 0800, Time out as 1630, and I'd like to get an answer of 8.5 for the number of hours worked. Not 8:30. No colons. Just decimals where half hours are displayed as .5.

      The formula below will return you the number of days between open & closing date:

      =INT(C1+D1-A1-B1)

      In order to calculate this duration in hours, please use the following formula instead:

      =TIME(,(C24+D24-A24-B24- INT(C24+D24-A24-B24)) *24*60,)

      Note! Don't forget to set the Time format for cell E1.

    I do have two columns with date and time. I want to calculate the difference between them (so, that is pretty easy, only subtract). My issue: 1. End date sometimes is "Null" - in that case I tried to solve by adding if and setting the difference time to 999 or so. 2. I would like output to be in Days, Hours, Minutes, but days shown only if they are >0; and I want result still be a number (for the graph later). Original fields are in format yyy-mm-dd hh:ss. Is there a way to display this? I believe it is possible to do with IF by putting "" if month value is 0, but won't that put the result to text field format? Also, that is pretty lengthy formula, maybe there is a function or format that I am not aware of?

  40. roxy says:

    How do you calculate the difference of day and time between days into minutes in one cell?

    for example:
    I have a email that came in last night at 8:30pm and i answered to the email at 10:30am the next day. How many minutes is in between of my response time?

    Also if it was during the weekend days how would it calculate the time?

    • Hello Roxy!
      I recommend reading the first part of the above article, 'How to calculate time difference in Excel', to answer your question.
      To be able to show more than 24 hours in a cell, please use this time format: "37:30:55". You can find it in the list of Excel time formats.

      If Saturday and Sunday are traditionally considered to be days off, it is possible to exclude those 2 days from calculations with the help of this formula:

      =IF(WEEKDAY(A3) < WEEKDAY(A2),A3-A2-2,0)

    Hi
    I have made a simple work schedule to show when each colleagues shift will be.
    I have a single cell displaying their start and end time (eg 10:00-14:00).
    the next column is for the number of hours in their shift.
    Is there a way I can get it to work out the number of hours in the shift automatically, or would I have to have a start and finish time in separate columns.
    I use the same sheet to print and put on the notice board so need it reader friendly.

    thanks!

    • Hello Louise!
      Of course, it’s better to record the start time and end time in two different columns. But in your case, you can use the following formula:

      =TIMEVALUE(MID(A10,FIND("-",A10,1)+1, LEN(A10)-FIND("-",A10,1))) - TIMEVALUE(LEFT(A10,FIND("-",A10,1)-1))

      Remember to apply the time format to the cell with this formula.
      I hope it’ll be helpful.

    In A1 i have a start time as 21:30:00 and in A2 an end time of 08:55:00 and have the formula of =IF(A2<A1,A1-A2+24,A2-A1)in A3; however A3 calculates as 12:35. Cells A1 and A2 set to [h]:mm:ss. Cells in A3 set to h:mm. I need A3 to calculate the actual time between 21:30 the previous evening to 08:55 the next morning in h:mm as the time of travel is through the night.

    Thanks.

    • Austin says:

      Note: A3 should calculate to 11:25 (11 hours and 25 minutes) elapsed time since commecing at 21:30:00, but calculates AS 12:35 (12 hours and 35 minutes).
      Thanks for your support.

    • Hello Austin!
      If I understand your task correctly, the following formula should work for you:

      =IF(A1 > A2,A2-A1+1,A2-A1)

      I hope this will help, otherwise please do not hesitate to contact me anytime.

    Hi,
    I have issue where I am entering time as text as we want to enter 9:00am in it's simplest form as 900 but have set format to 00":"00 which works well until you do calcualtions and sum totals.
    I have a spreadsheet with 2 examples on it but not sure if I can send to you:-
    !) entering time as text
    2) entering time as time
    both have there issues. We need to enter start time, end time then set a default for 30 min break which can be over typed with longer break (or if less than 5 hours worked no break) and sum the days paid hours.
    Hope you are able to give me some guideance on this.
    thanks, Chris

    • hello Chris!
      I'm sorry, it is not very clear what result you want to get. If you enter the number 900 in a cell, then you can convert it to time in another cell. Regardless of the format, a number, not time, will remain in this cell. Could you please describe your task in more detail and send us a small sample workbook with the source data and expected result to support@ablebits.com? Please shorten your tables to 10-20 rows/columns and include the link to your blog comment.

    • Hello Sheree L!
      The formula below will do the trick for you:

      =DATEVALUE(SUBSTITUTE(B1,",",""))+TIMEVALUE(SUBSTITUTE(B1,",","")) - DATEVALUE(SUBSTITUTE(A1,",",""))-TIMEVALUE(SUBSTITUTE(A1,",",""))

      or

      =SUBSTITUTE(B2,",","")-SUBSTITUTE(A1,",","")

      Remember to set the time format in this cell.

      Most likely, you have a non-printable character in front of the date. You cannot see him. This often happens when importing data from other programs into Excel.

    Mr. Trifuntov,
    I'm creating an excel file to manage the shifts of a restaurant and I'm having trouble to manage sums. The working shifts in most cases are divided in two (morning - evening). The columns represent the days of the week. For each worker / day I have four cells (morning (entry/exit) - evening (entry/exit). The problem arises when I don't include information in all the cells (because it is a day off/ the restaurant is close or the worker makes a continuous shift. The result in this case gives me as a result 00:00. When I want to calculate the total working hours during the week (sum) computes the 00:00 as 24 hours. What I can do to resolve this issue?.

    Hi, I just want to simply be able to subtract times in order to get the number of hours worked. For example, in the first column is 10:00 AM (A1), in the second column is is 2:20 PM (B1).

      Go to the cell in question (the one that is showing you 4:20 AM) and then go to Number Format, scroll down to More Number Formats, (alternatively you can just right click, then click Format Cells), on the Number tab click TIME, under "Type" click 13:30. This will give you your answer in the format I think you want: 4:20 meaning 4 hours and 20 minutes worked.

    I have a timesheet and I would like to have a calculation that subtracts the end time worked from the start time worked but have it subtract 30 minutes if it is over 6 hours elapsed and also subtract 30 additional minutes if it is over 8 hours elapsed. We have part time and full time staff. There are also some full time staff who work longer hours and get an hour for lunch instead of a half hour. I have tried to modify this:
    =IF(ISERR(O28-N28),N28,MOD(O28-N28,1)-(MOD(O28-N28,1)*24>6)/48)
    which subtracts the 30 minutes but does not account for the staff that stays longer and takes an hour lunch.
    I have this
    =TEXT(O28-N28, "h:mm")-("0:30")
    but it just assumes the calculation is over 8 hours and subtracts 30 minutes.
    I am stuck. Any help would be greatly appreciated.

    I need help writting a formula that sums minutes between two specific times, for example start 9:10am - end 9:45am. I need to sum how many minutes were between 9:00am and 9:30am (20 min) and how many between 9:30 and 10:00am (15 min).

  67. Amber says:

    I am trying to create a spreadsheet to calculate labor pool hours in a spreadsheet when the employee is unable to clock in onsite and they are reporting IN and OUT punches. However, we use Kronos which rounds to quarter hours (example: if an employee clocks in at 8:07 am, it rounds back to 8:00 am but if they clock in at 8:08 am, it rounds forwards to 8:15 am.) If I were trying to add their IN and OUT punches to a spreadsheet and have a total time worked, is there a way to have it automatically take in to account the Quarter Rounding aspect of Kronos time to give them an accurate total time worked?

    Need Excel formula for calculating the hours and minutes between to different AM and PM high tides. The two different AM (A1) and PM (B1) times could be different. The A2 could be a higher number then the B1 time number and vise versa. Need this formula for calculating this for each day of the year.

    How to get diff in days,hours,minutes,seconds,milli seconds for below
    Min time stamp: 2019-06-14 09:16:13.013
    Max time stamp: 2019-09-14 09:16:12.310

    • Hello!
      Find the difference between these dates using normal subtraction. To determine the difference in time in days, hours, minutes and seconds, apply the formula to the cell with the result:

      =INT(A1)&" days "&INT(MOD(A1,INT(A1))*24)&" hours and "&MINUTE(A1)&" minutes, "&SECOND(A1)&" seconds"

      I hope my advice will help you solve your task.

      • Venkat says:

        I need for milliseconds as well. Above works until seconds only.

        • Venkat says:

          Hi Alexander Trifuntov (Ablebits.com Team),

          =INT(A1)&" days "&INT(MOD(A1,INT(A1))*24)&" hours and "&MINUTE(A1)&" minutes, "&SECOND(A1)&" seconds"

          Can you also add calculation for milliseconds as well in above?

    Hello.
    I'm looking for a formula. I made one that gives the total worked hours. But my problem is, let's say the office time starts at 8am, the formula includes the time over or under 8am which the minutes for late and early in is computed.

  75. Daniel Rasmussen says:

    hey so i have a timesheet for work i need it to calculate total hours, overtime 1 and overtime 2
    where hours from 07:00-15:00 is normal hours so no overtime counted
    hours from 15:00-17:00 is counted in overtime 1
    and all other hours is counted in overtime 2
    like so
    if A1(start time)=07:00 B1(end time)=19:00 C1(total hours)=12 D1(overtime1)=2 E1(overtime2)=2
    or A1(start time)=04:00 B1(end time)=16:00 C1(total hours)=12 D1(overtime1)=1 E1(overtime2)=3

  76. narusha says:

    Hey I have a timesheet that I would like to calculate the specific hours given is counted as overtime 1 which is from 22:00 PM - 06:00 AM, time after 06:00 AM will be calculated as overtime 2. I wanna get the hours worked in oveRtime 1 is how many hours? is that possible.
    For example:
    TIME IN (A1) = 12:00AM
    TIME OUT (B1) = 11:00 AM
    hours worked in overtime 1 is 8 hours, and in overtime 2 is 5 hours.

    Hi there!

    I'm trying to track improvement in running times (e.g. how much faster someone is running 5km).
    So I was wondering if it is possible to subtract one running time (35 minutes 10 seconds) from a better running time (25 minutes 30 seconds) to see how much faster someone is running (-9 minutes 45 seconds).

    I need to figure out how can i get event time/run time of every account having multiple transactions, i need time duration between First till last transaction of every account, every account having multiple transactions count.

  79. Travis Noffke says:

    I am making a spreadsheet to fully calculate how much pay I'm getting the only variable I'm stuck on is that I get paid %15 extra/hour after 6pm on weekdays. Is there a formula that checks for a time after 6pm and can return a value?

    Thank you if anyone can help.

  80. Eya says:

    what's the added formula if 1 hour must be deducted if you accumulated 6 hrs of overtime everyday?

  81. Alphonse says:

    John,
    Wouldn't that cause a circular reference?
    C9: 8:30
    B9: 19:30 (which baffles me to put the End time in B and Stat time in C...?)
    Then, in D9, we subtract those two AND subtract D9 itself from that?... ???

  82. Sabi says:

    hello, how to calculate times between 9AM-9PM and 9PM-9AM if I have '14-Jan-20 05:00' (F2) as a reported date and '15-Jan-20 13:00' (G2) as a resolved date? Thank you in advance :)

  83. kyaw says:

    1st condition = should be after 8:30 AM
    2nd condition = should be before 4 PM
    Cannot find the right date. Struggle with AM/PM thing (confuse)
    for eg.

    =if(and(10:20 AM>=8:30 AM,10:20 AM<=4:30 PM),"within","out")

    note: 10:20 here is random time.
    Could you help whats wrong with formula and how can I get the right condition?

  84. Cindy says:

    Good afternoon, I have some days where I clock in at 5:00 am out at 11:00 back in 30 minutes later and then out at 1:30pm. But then there are some days in which I will be in and out 3-4 days in a day. example would be Monday 5:00 - 11:00, back in at 11:30 and work till 1:30. But today because I have to go into the office it would be 5:00 - 8:30, 9:15 - 10:30, 12:00 - 2:00, 4:00 - 6:00 pm. I have tried using: =IF(OR(B2="",I2=""),"",(C2-B2)+(E2-D2)+(G2-F2)+(I2-H2)) but the time will not round and I'm still coming up short. Whatever suggestion you have it would be TRULY APPRECIATED because I hate to have to make up time when I'm short 1 day and over the next.
    Sincerely,
    Frustrated!!!

      Hi Alexander, I need a formula that tracks multiple times that I would clock in and out of work. Clock in the morning, then clock out for break, back in from break, then out for lunch, clock back in from lunch, then out for break, then return from break, then out for a second afternoon break then clock back in from that break until I clock out for the day.

      example:
      clock in at 5:00 AM, out at 7:00 for 30 minutes then i clock back in at 7:30, work from 7:30 until 11:00 then it's lunch from 11:00 am until 11:30 then i clock back in, then at 1:00 PM I clock out for 30 minutes and return at 1:30 until the end of my shift.

      so any formula you could share would be greatly appreciated.

  86. Heather says:

    Hello, I need a formula that will help me determine how many calls were happening at 3:00 PM on 11/16. I need to figure out if 11/16/2020 3:00 PM falls between two dates and times.

    For example in row 2 I have join time and leave tine columns with the following data:
    I2: 11/16/20 1:00 PM J2: 11/16/20 1:01 PM
    I3: 11/16/20 13:40 J3: 11/16/20 14:30

    I have about 200 rows with date and times to go through so I need to see if the 11/16/20 3:00 PM date and time falls in between the dates above as well as the other rows. I need an output for each row (whether its true or false).

    After I get this data I can use a count formula to see how many times I get yes which will determine how many calls were happening at 3:00 PM on 3/16.

    My data expands over 48 hours.

    Hello!

    I need a formula which counts the transaction from (Date, 00:00:01 to 23:59:59) 24 hours and the count after 23:59:59 should go to next date.

    • Hi,
      I’m sorry but your task is not entirely clear to me. Could you please describe it in more detail? What result do you want to get? Give an example of the source data and the expected result.

        Hello Alexander,

        I am trying to figure out a formula, which will calculate the transaction counts for a day (example: total transaction count for 18-Nov-20 (00:00:01 to 23:59:59) will be 100nos). Also, the counts that are calculated after (18-Nov-20 (00:00:01 to 23:59:59)) should fall to next day (19-Nov-20).

        Is there any formula that you can suggest?

  88. Steph says:

    is it possible for the below formula to be working days not just days??

    =IF(INT(M5-I5)>0, INT(M5-I5) & " days, ","") & IF(HOUR(M5-I5)>0, HOUR(M5-I5) & " hours, ","") & IF(MINUTE(M5-I5)>0, MINUTE(M5-I5) & " minutes and ","")

    TIA

    • Hello!
      I believe the following formula will help you solve your task:

      {=SUM(--(WEEKDAY(ROW(INDIRECT(INT($A$1)&":"&INT($B$1))),2) < 6))-2 + B1-A1-INT(B1-A1)+(MOD(B1,INT(B1)) > MOD(A1,INT(A1)))}

      This is an array formula and it needs to be entered via Ctrl + Shift + Enter, not just Enter.

      Use custom date format

      d "d." h "h."m" min."

      I hope I answered your question.

    =IF(B2<A2,B2+1,B2)-A2 I AM USING THIS FORMULA TO FIND TOTAL WORKING HOURS OF AN EMPLOYEE.
    IF ONE EMPLOYEE ABSENT MEANS I ENTER ZERO VALUES IN TIME IN AND TIME OUT CELL .BUT ITS NOT WORK.
    MY DOUBT IS IF ONE EMPLOYEE ABSENT MEANS HOW TO AND VALUE ENTER IN TIME IN AND TIE OUT CELL.

    • Hello!
      Sorry, I do not fully understand the task. If A2 and B2 are 0, the formula returns 0. Please describe your problem in more detail.
      Explain exactly what the problem is. Give an example when the error appears. It’ll help me understand the problem you faced better and help you.
