*This tutorial will teach you a few quick and easy ways to find out how many days are between two dates in Excel.*

Are you wondering how many days between two dates? Maybe, you need to know the number of days between today and some date in the past or future? Or, you just want to count working days between two dates? Whatever your problem is, one of the below examples will certainly provide a solution.

If you are looking for a quick answer, just supply the two dates in the corresponding cells, and our online calculator will show you how many days there are from date to date:

Curious to know the formula that has calculated your dates? It's as simple as `=B3-B2`

:)

Below you will find the detailed explanation on how this formula works and learn a few other methods to calculate days between dates in Excel.

The easiest way to calculate days between dates in Excel is by subtracting one date from another:

For example, to find out how many days are between dates in cells A2 and B2, you use this formula:

`=B2 - A2`

Where A2 is an earlier date, and B2 is a later date.

The result is an integer that represents no. of days between two dates:

As you probably know, Microsoft Excel stores dates as serial numbers starting on 1-Jan-1900, which is represented by the number 1. In this system, 2-Jan-1900 is stored as the number 2, 3-Jan-1900 as 3, and so on. So, when subtracting one date from another, you actually subtract the integers representing those dates.

In our example, the formula in C3, subtracts 43226 (the numeric value of 6-May-18) from 43309 (the numeric value of 28-Jul-18) and returns a result of 83 days.

The beauty of this method is that it works perfectly in all cases, no matter which date is older and which is newer. If you are subtracting a later date from an earlier date, like in row 5 in the screenshot above, the formula returns a difference as a negative number.

Another way to count days between dates in Excel is by using the DATEDIF function, which is specially designed to work out the date difference in various units, including days, months and years.

To get the number of days between 2 dates, you supply the start date in the first argument, end date in the second argument, and "d" unit in the last argument:

DATEDIF(start_date, end_date, "d")

In our example, the formula goes as follows:

`=DATEDIF(A2, B2, "d")`

Unlike the subtraction operation, a DATEDIF formula can only subtract an older date from a newer date, but not the other way round. If the start date is later than the end date, the formula throws a #NUM! error, like in row 5 in the screenshot below:

The users of Excel 2013 and Excel 2016 have one more amazingly simple way to calculate days between two dates - the DAYS function.

Please pay attention that compared to DATEDIF, a DAYS formula requires the arguments in the reverse order:

DAYS(end_date, start_date)

So, our formula takes the following shape:

`=DAYS(B2, A2)`

Like subtraction, it returns the difference as a positive or negative number, depending on whether the end date is greater or smaller than the start date:

In fact, calculating the number of days from or before a certain date is a particular case of "how many days between dates" math. For this, you can use any of the formulas discussed above and supply the TODAY function instead of one of the dates.

To calculate the number of days **since date**, i.e. between a past date and today:

TODAY() - *past_date*

To count the number of days **until date**, i.e. between a future date and today:

As an example, let's calculate the difference between today and an earlier date in A4:

`=TODAY() - A4`

And now, let's find out how many days are between today and a later date:

In situations when you need to get the number of working days between two dates, use the NETWORKDAYS function:

NETWORKDAYS(start_date, end_date, [holidays])

The first two arguments should already look familiar to you, and the third (optional) argument allows excluding a custom list of holidays from the day count.

To find out how many working days are between two dates in columns A and B, use this formula:

`=NETWORKDAYS(A2, B2)`

Optionally, you can enter your holiday list in some cells and tell the formula to leave out those days:

`=NETWORKDAYS(A2, B2, $A$9:$A$10)`

As the result, only business days between two dates are counted:

As you see, Microsoft Excel provides a handful of different ways to count days between dates. If you are not sure which formula to use, let our Date & Time Wizard do the how-many-days-between-two-dates calculation for you. Here's how:

- Select the cell in which you want to insert the formula.
- On the
*Ablebits Tools*tab, in the*Date & Time*group, click**Date & Time Wizard**:

- In the
*Date & Time Wizard*dialog window, switch to the**Difference**tab and do the following:- In the
*Date 1*box, enter the first date (start date) or a reference to the cell containing it. - In the
*Date 2*box, enter the second date (end date). - In the
*Difference in*box, select**D**.

The wizard immediately shows a formula preview in the cell and the result in the

*Difference in*box. - In the
- Click the
**Insert formula**button and have the formula inserted in the selected cell. Done!

A double-click on the fill handle, and the formula gets copied across the column:

To display the date difference in a slightly different way, you are free to choose any of the additional options:

*Show text labels*- the word "days" will appear along with the number, like shown in the screenshot below.*Do not show zero units*- if the date difference is 0 days, an empty string (blank cell) will be returned.*Negative result if Date 1 > Date 2*- the formula will return a negative number is the start date is later than the end date.

The screenshot below shows a couple of additional options in action:

how to calculate times difference.

if start date and start time in different column and end date and end time are in different column than how to calculate.

Nitesh:

The formula is ((End Date + End Time)-(Start Date + Start Time))*24

Format each cell the way you usually do for each variable.

Format the result cell as General or Number.

Very informative and useful for me.

Thank you.

In testing, it appears the DATEDIF does not compute date values prior to Jan 1, 1900. What's the solution for computing date different (age, for example), if the birth date is in the late 1800s?

Matt:

According to Microsoft there is a VBA Macro you can use.

Hi

I am trying to total the number of days a certain job takes to do. However if the task is done in the same day how do I get excel to count this as 1 day?

Any feedback would be super - thank you

Danielle

Hi Danielle,

Assuming that your dates and in A and B columns, the formula below should work for you:

=IF(B1=A1,1,B1-A1)

Just enter this formula in C1 and then copy it along the column.

If you have any questions, don't hesitate to ask.

What if I wanted to use this formula with "B1" being "Today"? I can't seem to make that work.

Hi,

I'm trying to do something similar to Danielle, but would like to calculate the number of days something is open, so I would need to use 3 dates to calculate this, date open, date closed and today.

Would anyone be able to help with the formula?

Thanks Vicky

Hello,,

Good Morning.

I need Deviation in days between Actual date and Desired date as per Planner,,

Example..

Cell A1 is last calibration date (22 August 2019)

Cell B1 is Next Calibration date (22 Sept 2019) calibration validity is 1 month.

Cell A 10 is calibration done date (27 sept 2019)

how to calculate the calibration deviation in the planner,,

I need to include start date as well end date so what to do. I just did A2-B2+1. any other formula

This counter is not that good... He counts first and last day. And then it is not correct. For example I need to count 90 days from 17 nov. Last day I get 15 febr. But it is not right - then I have 91 day!!! He should not count the last day...

If the date format in your excel sheet does not reflect what is displayed on your windows taskbar, then this may not work for you. In order to fix this you can change your Regional format data with the following instructions:

Right-click on time and choose "adjust date/time"

Under related settings choose "Date, time, & regional formatting"

Under Regional format data choose "Change data formats"

Select the short date format that works for you

Bask in the glory of solving this mystery that plagued me for longer than I care to mention.

Hi

I need to enter a third date into the argument. I am counting the number of days elapsed between a date in the past (say in cell A1) and 'TODAY' (say the formula is in Cell A2) , but I then need to add in a completion date (say in cell A3) and need the number of days to stop counting once the completion date is entered. How do I tell the formula to stop counting when that completion date is entered? Oh, I also need to tell the formula that if A1 is blank, leave A2 blank. So at the moment my formula would look like this:

=IF(ISBLANK(A1),"",(TODAY()-A1))
