How to add and subtract dates, days, weeks, months and years in Excel

In this tutorial, you will find a variety of useful formulas to add and subtract dates in Excel, such as subtracting two dates, adding days, weeks, months and years to a date, and more.

If you have been following our tutorial to working with dates in Excel, you already know an array of formulas to calculate different time units such as days, weeks, months and years.

When analyzing the date information in your worksheets, you are likely to perform some arithmetic operations with those dates too. This tutorial explains a few formulas for adding and subtracting dates in Excel that you may find useful.

How to subtract dates in Excel

Supposing you have two dates in cells A2 and B2, and now you want to subtract one date from the other to know how many days are between these dates. As is often the case in Excel, the same result can be achieved in several ways.

Example 1. Subtract one date from the other directly

As you probably know, Microsoft Excel stores each date as a unique serial numbers beginning with 1 that represents January 1, 1900. So, you are actually subtracting two numbers, and an ordinary arithmetic operation works without a hitch:

=B2-A2

Example 2. Subtract dates using Excel DATEDIF function

If the above formula looks too plain, you can achieve the same result in a guru-like way by using Excel's DATEDIF function:

=DATEDIF(A2, B2, "d")

The following screenshot demonstrates that both calculations return identical results, except for row 4 where the DATEDIF function returns the #NUM error. Let's figure out why that happens.

When you subtract a more recent date (6-May-2015) from an earlier date (1-May-2015), the subtraction operation returns a negative number (-5) exactly as it should. The syntax of the Excel DATEDIF function, however, does not allow the start date to be greater than the end date and therefore it returns an error.

Example 3. Subtract a date from the current date

To subtract a date from today's date, you can employ either of the above formulas. Just use the TODAY() function instead of date 1:

=TODAY()-A2

or

=DATEDIF(A2,TODAY(), "d")

Like in the previous example, both formulas work fine when today's date is greater than the date you are subtracting from it, otherwise DATEDIF fails:
Subtracting a date from the current date in Excel

Example 4. Subtracting dates using the Excel DATE function

If you prefer to supply the dates directly in the formula, then enter each date using the DATE(year, month, day) function and then subtract one date from the other.

For instance, the following formula subtracts 15-May-2015 from 20-May-2015 and returns the difference of 5 days:

=DATE(2015, 5, 20) - DATE(2015, 5, 15)
Subtracting dates using the Excel DATE function

Wrapping up, when it comes to subtracting dates in Excel and you want to find out how many days are between two dates, it makes sense to go with the easiest and most obvious option - simply subtract one date directly from another.

If you are looking to count the number of months or years between two dates, then the DATEDIF function is the only possible solution and you will find a few formula examples in the next article that will cover this function in full details.

Now that you know how to subtract two dates, let's see how you can add or subtract days, months, or years to a given date. There are a number of Excel functions suitable for this purpose, and which one you use depends on which unit you want to add or subtract.

How to subtract or add days to date in Excel

If you have a date in some cell or a list of dates in a column, you can add or subtract a certain number of days to those dates using a corresponding arithmetic operation.

Example 1. Adding days to a date in Excel

The general formula to add a specified number of days to a date in as follows:

=Date + N days

The date can be entered in several ways:

  • As a cell reference, e.g. =A2 + 10
  • Using the DATE(year, month, day) function, e.g. =DATE(2015, 5, 6) + 10
  • As a result of another function. For example, to add a given number of days to the current date, use the TODAY() function: =TODAY()+10

The following screenshot demonstrates the above formulas in action. The current date at the moment of writing was 6 May, 2015:
Adding days to a date in Excel

Note. The result of the above formulas is a serial number representing the date. To get it displayed as a date, select the cell(s) and press Ctrl+1 to open the Format Cells dialog. On the Number tab, select Date in the Category list, and then choose the date format you want. For the detailed steps, please see How to change date format in Excel.

Example 2. Subtracting days from a date in Excel

To subtract a given number of days from a certain date, you perform a usual arithmetic operation again. The only difference from the previous example is that you type the minus sign instead of plus :)

=Date - N days

Here are a few formula examples:

  • =A2 - 10
  • =DATE(2015, 5, 6) - 10
  • =TODAY() - 10

Subtracting days from a date in Excel

How to add or subtract weeks to date

In case you want to add or subtract whole weeks to a certain date, you can use the same formulas as for adding / subtracting days, and simply multiply the number of weeks by 7:

Adding weeks to a date in Excel:

=A2 + N weeks * 7

For example, you add 3 weeks to the date in A2, use the following formula: =A2+3*7.

Subtracting weeks from date in Excel:

=A2 - N weeks * 7

To subtract 2 weeks from today's date, you write =TODAY()-2*7.

How to add / subtract months to date in Excel

If you want to add or subtract a certain number of whole months to a date, you can employ either the DATE or EDATE function, as demonstrated below.

Example 1. Add months to a date with Excel DATE function

Taking a list of dates in column A for example, type the number of dates you want to add (positive number) or subtract (negative number) in some cell, say C2.

Enter the following formula in cell B2 and then drag the corner of the cell all the way down to copy the formula to other cells:

=DATE(YEAR(A2), MONTH(A2) + $C$2, DAY(A2))
Adding months to a date with Excel DATE function

Now, let's see what the function is actually doing. The logic behind the formula is obvious and straightforward. The DATE(year, month, day) function takes the following arguments:

  • the year of the date in cell A2;
  • the month of the date in A2 + the number of months you specified in cell C2, and
  • the day of the date in A2.

Yep, it's that simple :) If you type a negative number in C2, the formula will subtract months instead of adding them:

Adding / subtracting months to a date with Excel DATE function

Naturally, nothing prevents you from typing the minus sign directly in the formula to subtract months from a date:

=DATE(YEAR(A2), MONTH(A2) - $C$2, DAY(A2))

And of course, you can type the number of month to add or subtract in the formula instead of referring to a cell:

=DATE(YEAR(date), MONTH(date) + N months, DAY(date))

The real formulas could look similar to these:

  • Add months to date: =DATE(YEAR(A2), MONTH(A2) + 2, DAY(A2))
  • Subtract months from date: =DATE(YEAR(A2), MONTH(A2) - 2, DAY(A2))

Example 2. Add or subtract months to a date with Excel EDATE

Microsoft Excel provides a special function that returns a date that is a specified number of months before or after the start date - the EDATE function. It is available in modern versions of Excel 2007, 2010, 2013 and upcoming Excel 2016.

In your EDATE(start_date, months) formulas, you supply the following 2 arguments:

  • Start_date - the start date from which to count the number of months.
  • Months - the number of months to add (a positive value) or subtract (a negative value).

The following formula used on our column of dates yields exactly the same results as the DATE function in the previous example:

Adding or subtracting months to a date with Excel EDATE formulas

When using the EDATE function, you can also specify the start date and the number of month to add / subtract directly in the formula. Dates should be entered by using the DATE function or as results of other formulas. For example:

  • To add months in Excel:=EDATE(DATE(2015,5,7), 10)

    The formula adds 10 months to 7-May-2015.

  • To subtract months in Excel:=EDATE(TODAY(), -10)

    The formula subtracts 10 months from today's date.

Note. The Excel EDATE function returns a serial number representing the date. To force Excel to display it as a date, you should apply the Date format to the cells with your EDATE formulas. Please see Changing the date format in Excel for the detailed steps.

How to subtract or add years to date in Excel

Adding years to a date in Excel is done similarly to adding months. You use the DATE(year, month, day) function again, but this time you specify how many years you want to add:

=DATE(YEAR(date) + N years, MONTH(date), DAY(date))

In your Excel worksheet, the formulas may look as follows:

  • To add years to a date in Excel:

    =DATE(YEAR(A2) + 5, MONTH(A2), DAY(A2))

    The formula adds 5 years to the date in cell A2.

  • To subtract years from a date in Excel:

    =DATE(YEAR(A2) - 5, MONTH(A2), DAY(A2))

    The formula subtracts 5 years from the date in cell A2.

If you type the number of year to add (positive number) or subtract (negative number) in some cell and then refer to that cell in the DATE function, you will get a universal formula:

Subtract or add years to a date in Excel

Add / subtract days, months and years to date

If you carefully observed the two previous examples, I think you have already guessed how to add or subtract a combination of years, months and days to a date in a single formula. Yep, using the good old DATE function :)

To add years, months, days:

=DATE(YEAR(date) + X years, MONTH(date) + Y months, DAY(date) + Z days)

To subtract years, months, days:

=DATE(YEAR(date) - X years, MONTH(date) - Y months, DAY(date) - Z days)

For example, the following formula adds 2 years, 3 months and subtracts 15 days from a date in cell A2:

=DATE(YEAR(A2) + 2, MONTH(A2) + 3, DAY(A2) - 15)

Applied to our column of dates, the formula takes the following shape:

=DATE(YEAR(A2) + $C$2, MONTH(A2) + $D$2, DAY(A2) + $E$2)

Add / subtract days, months and years to date

How to add and subtract times in Excel

In Microsoft Excel, you can add or subtract times using the TIME function. It lets you operate on time unites (hours, minutes and seconds) exactly in the same way as you handle years, months and days with the DATE function.

To add time in Excel:

=A2 + TIME(hours, minutes, seconds)

To subtract time in Excel:

=A2 - TIME(hours, minutes, seconds)

Where A2 contains the time value you want to change.

For example, to add 2 hours, 30 minutes and 15 seconds to the time in cell A2, you can use the following formula:

=A2 + TIME(2, 30, 15)

If you want to add and subtract time unites within one formula, just add the minus sign to the corresponding values:

=A2 + TIME(2, 30, -15)

The above formula adds 2 hours and 30 minutes to the time in cell A2 and subtracts 15 seconds.

Alternatively, you can enter the time unites you want to changes in some cells, and refer to those cells in your formula:

=A2 + TIME($C$2, $D$2, $E$2)

Adding and subtracting times in Excel

If the original cells contain both date and time, the above formula works perfectly too:
Adding and subtracting times to a date and time

This is how you add and subtract dates in Excel. I am hopeful you have learned a couple of useful functions today. Anyway, I thank you for reading and hope to see you on our blog next week.

  5. Mechele says:

    Hello,
    how do I determine the difference between 2 dates, and also show a "0" if the start date is greater than the end date

    • Hi Mechele,

      You can use a simple IF formula, for example:

      =IF(A1>B1, 0, B1-A1)

      Where A1 is the start date and B1 is the end date.

      In a similar manner, you can use the DATEDIF function to calculate the difference between two dates in days, weeks, months or years:

      =IF(A1>B1, 0, DATEDIF())

    Hi Irfan,

    The simplest format I can assume from what you specify is as follows:

    Step 1 - Cell A1 type in the "From" date.
    Step 2 - Cell B1 type in the "To" date.
    Step 3 - Cell C1 type in the fomula "=B1-A1+1. We add one to include the start date. You will then get the number of days.
    Step 4 - In Cell D1 enter the formula to multiply Cell C1 by 24 to get the hours.
    Step 5 - In Cell E1 multiply Cell D1 by 60 to get the number of minutes.
    Note - If you enter the date function in Cell B1 as "=NOW()" then you will get the live time set in excel. This will assist you in getting the calculation of days and minutes, in decimal point, if you wish to.

    Regards,
    Ramki

  10. Ramki says:

    Hi Jules,

    I assume that the data relating to dates must be a part of a greater data range. The solution to this is as follows:

    Convert the data range to a Table using the Ctrl-T function. You will observe that all the column headings will have a drop-down filter. Click on the filter of the date column and select Date-filters - you will see a wide range of options. In excel 2013 there are 20 options with two more custom options.
    I am sure that you will be able get the required results you need.

    The specific requirement for this sort of filtering is the data in the date column should be entered in date format as per excel predefined formats.

    • Sorry, it's hard to think about ways of getting data without seeing your table. If the "Previous Experience" column has a string value, you can try the following:

      To get the number of years and months from Previous Experience you can use formulas like these:
      =LEFT(D3, SEARCH(" ", D3, 1)) - for years

      =MID(D3, SEARCH("years", D3, 1)+5, SEARCH("months", D3, 1) - (SEARCH("years", D3, 1)+ 5)) - for months

      If the "Total Year Experience" column is countable, add the results to the formula for this column.

    Once these two fields are entered, I'd like a group of cells to be updated with the dates.

    For example:

    Week Number: 22
    Month: June

    30 31 1 2 3 4 5

    I haven't found any information on how to accomplish this.

    If I have no date can I return a blank cell?

    =IFERROR(MONTH(BA5),"") IS RETURNING 1

    Thanks Svetlana, im new to this!

    hi,

    i want to split day and date so how to possible ?

    • Hello Hiren,

      If your original values are dates, you can use the following formulas:

      To extract the day of the week: =TEXT(A2, "dddd")
      To extract the date: =TEXT(A2, "mmmm dd, yyyy")

      If your original values are text strings, then use these ones:

      To extract the day of the week: =LEFT(A2, FIND(",", A2)-1)
      To extract the date: =RIGHT(A2, LEN(A2)-FIND(",", A2)-1)

    Hi,

    I have added 12 months to a date in column E4, but if there is not a date to add to (E4 is blank) then the date shows 31/12/1900. How do I make the cell blank rather than 31/12/1900? I'm having trouble adding an IFBLANK function to the below formula. Thanks :)

  38. SElizabeth says:

    I'm trying to develop a spreadsheet of pregnant patients, and I need a formula to calculate today's gestational age from due date. The output would be something like "35 2/7", meaning 35 weeks and 2 days gestation. Here's the Google Sheets formula that does not work in Excel:

    =ArrayFormula(if(A1:A,int((280-(A1:A-today()))/7)&ʺ ʺ&mod(280-(A1:A-today()),7)&ʺ/7ʺ,iferror(1/0)))

  39. Lori says:

    I am looking for a similar calculation as SElizabeth. What I need is a gestational age calculated from a specific due date on a specific date. All I can locate is a formula that gives a calculation based on todays date...which of course will change the resulting value each day. I need for the result to be a fixed value.

    The formula I have is: =FLOOR(279-(K2-TODAY()),7)/7&" weeks "&MOD(279-(K2-TODAY()),7)&" days"

    The K2 value is clients due date. When I try to substitute the TODAY value for a cell that contains the date I want this to calculate off of, I get an error.

    I don't understand excel at all...so I am stuck!

    Any ideas?

    Thanks

    Hi! Is it possible to do math with dates which are formatted 3.4.2016? So separated with dots in other words.

  42. Sandy says:

    I am trying to subtract two dates to get a calculated time between the dates in MM:dd:hh:mm format to see how long it takes to resolve an ticket. Example:

    Start Date: 05/01/2016 13:24
    End Date: 05/17/2016 18:04

    Should end up with 00:16:04:40, but it comes out as 01:16:04:40, and I can't for the life of me figure out how to make that month be 00 and be more accurate.

    I have found several articles that use the ability to manipulate the month itself, but doesn't describe how to subtract two dates AND round down on the month to show the accurate time between the two dates. Any help here would save what hair I have left. Thanks.

    • Hi Sandy,

      You can use DATEDIF to get the number of complete months between 2 dates, and then concatenate the results of several functions in 1 formula:

      =DATEDIF(A1,A2,"m") & ":" & DATEDIF(A1,A2,"d") & ":" & TEXT(TIME(HOUR(A2), MINUTE(A2), SECOND(A2)) - TIME(HOUR(A1), MINUTE(A1), SECOND(A1)), "hh:mm")

      Where A1 is the start date, and A2 is the end date.

      The drawback of this approach is that the result is a text string and you won't be able to use it in other calculations.

      • Sandy says:

        Yes that's the problem. I do need to be able to add the results of this together to get a total time spent on a ticket. Any other ideas?

        • Sorry, I have no other idea. To my best knowledge, none of the Excel functions or formats can display a zero month or day.

          As a workaround, you can use 1 column to present the time difference in an easy-to-understand way (DATEDIF formula). And in another column, calculate the time difference with a simple formula like =A2-A1, and display it in hours and minutes [hh]:mm. And then, use that second column to get the total time.

    HI,,,
    Hope you doing well in the best of health. I really like the page, which is much helpfull. I need help please guide me.
    I am doing job at college and we deal majority student matters.
    if a student deposit his/her fee after due date, and due date is e.g 25-09-2016 and deposit date is 27-10-2016. each day after due date will b charge as fine Rs. 100. how i will do it with formula........please help

    • Hi Naveed,

      Assuming the due date is in A2, and the actual payment date in B2, and the fine is 100 per day, you can calculate the fine amount with this formula:

      =IF(B2>A2, (B2-A2)*100, 0)

      If necessary, you can add the fine to the original amount, which is, say, in cell C2:

      =IF(B2>A2, (B2-A2)*100+C2, C2)

    Hi all,

    Following this thread and trying to create a list in Column A to reflect a weekly schedule with the value in A3 being the baseline and incrementing A4, A5, etc... by 7 days, simple stuff based on this site... so I thought... ;)

    Desired results
    Cell A3 - 1/10/2017
    Cell A4 - 1/17/2017
    Cell A5 - 1/24/2017
    etc...

    Current configuration
    Cell A3
    - Format: Date (3-14-2012 from Date format Type list)
    - Current value: 1/10/2017

    Cell K1
    - Format: Number
    - Current value: 7

    Cell A4
    - Format: Date (3-14-2012 from Date format Type list)
    - Formula: =DATE(YEAR(A3),MONTH(A3),DAY(A3)+$K$1)
    - Resultant value: #VALUE!

    Investigation
    I'm on Office2016 64-bit on a WINDOWS7 64-bit, i7 CPU/16GB RAM

    If I go to Cell A3 and "drag down" to A4 the date increments to 1/10/2018 so it seems as though it is recognized as a date...

    Looking at the Function bar dialog box when you click on "fx" it shows:

    /snip

    DATE
    Year: YEAR(A3) = #VALUE!
    Month: MONTH(A3) = #VALUE!
    Day: DAY(A3)+$K$1 = #VALUE!

    Formula result =

    /snip

    I then look at "Evaluate formula" and get (CY2017 is the tab name):

    /snip

    Reference Evaluation
    'CY2017'!$A$4 = DATE(YEAR("1-10-2017"),MONTH(A3),DAY(A3)+$K$1)

    The next evaluation will result in an error.

    /snip

    No change if I modify Date "type" format or change "/" to "-"...

    Questions
    Why would the date not format to 1-10-2016 per the selected Date format?
    - I went to a blank cell and modified the cell format to the same as above, when I then enter 1/10/17 it changes to 2001-10-17... huh??

    Appreciate any insight, thanks.

    Well after googling several add month solutions it appears that the 2 solutions actually do not work as I would expect them.

    How do you actually get the last day of the month based on the last day of the previous month ?

    If I add 1 month for example to the last day of September 2015 i.e:
    A1=date(2015,09,30) := 2015-09-30
    A2=date(year(A1),month(A1)+1,day(A1)) := 2015-10-30
    This is 1 day before the last day of October 2015.
    So it isn't adding 1 month but 1 month minus 1 day.

    I was expecting to get as a result: 2015-10-31

    Same result using EDATE
    A1=date(2015,09,30) := 2015-09-30
    A2=EDATE(A1,1) := 2015-10-30

    The only way I found to get this to work i.e: get the date of the last day of the month based on previous last day of the month is:

    A1=date(2015,09,30) := 2015-09-30
    A2=DATE(YEAR(A1+1),MONTH(A1+1)+1,DAY(A1+1))-1 := 2015-10-31

    • Tim R says:

      The EOMONTH formula will return the last day of the month, and you can specify how many months before or after your original date. e.g. if your original date is in cell A1, =EOMONTH(A1,3) will return the last day of the month three months later. I hope that helps.

    Hi I need a formula to know the number of days a project is delayed
    Ex.
    No. of day required days = 7 days
    Start date = March 20, 2017
    End date = March 24, 2017

    What formula can I use to reflect no. of days a project is advanced or delayed. Excluding Sat Sun and holidays

    • Hi Ron,

      Let's say that start day is in A1, end date is in B1.
      First of all, you need to count the number of working days between your dates in C1:
      =NETWORKDAYS(A1,B1)
      You can find out how to exclude weekends and holidays here.

      Then, depending on how you want the result to return:
      a) if as a text in D1, enter the next formula there:
      =IF(C1<=7,"Advanced","Delayed")

      b) if you want to fill C with a colour, create formatting rules using formulas:
      =AND($C1<=7,$C1<>"") (green colour for advanced)
      and
      =AND($C1>7,$C1<>"") (red, meaning delayed)
      Apply the formatting for =$C:$C column.

      Hope it helps!

    Why is there a difference when both formulas are supposed to yield the same, namely one month from 3/31/2017?

    What am I missing?

    • Hi, James,
      it is a very interesting notice! DATE and EDATE functions treat the months in slightly different ways. EDATE adjusts the results by adding a whole month (but since April consists of 30 days, its last day is shown). DATE, in its turn, adds the same number of days, but the 31st day is treated by the function as the 1st day of the next month. Please, look at the example below to get a clear understanding.

    Hey!
    I'm trying to use dates for my study spreadsheet, and I have the end of semester date - Todays date which gives me my total days left. This is great, except I now want to subtract every thurs and fri (for work) from that! And I want this to constantly self update, so that when I pass those days, that subtraction is no longer reflected in the total. I also then want to subtract a specific two weeks (date to date)also for a trip in between.

    Please help :)

  90. Mark Crowder says:

    How would I go about adding 90 days to a date. I am looking to add 90 days from one column to another.

  91. Derrick says:

    I have a column formatted as date YYYY-MM-DD, and I am using your formula to add 50 to the year.
    I used
    =DATE(YEAR(E2)+50,MONTH(E2),DAY(E2))
    I thought this would be simple, but I am getting a Value error. I am obviously missing something simple, but I am having one of those days

    Any help would be appreciated. Thanks

      I discovered the problem, Excel thinks the world started after 1900. My dates were 1800s and Excel does not recognize anything before 1900 as a date.
