# How to calculate the difference between two dates in excel

Calculating the number of days between two dates in Excel is a relatively simple task, and can be done using the “DATEDIF” function. This function allows you to specify the start date, end date, and unit of time you want to use to calculate the difference. For example, to calculate the number of days between 1/1/2022 and 1/5/2022, you would use the following formula:

=DATEDIF(A1, B1, “d”)

Where A1 is the cell containing the start date, and B1 contains the end date. The “d” indicates that you want to calculate the difference in days.

### Calculate the difference between dates in months or years

You can also use the “DATEDIF” function to calculate the months or years between two dates. To do this, simply change the unit of time from “d” to “m” for months, or “y” for years. For example, to calculate the number of months between 1/1/2022 and 1/5/2022, you would use the following formula:

=DATEDIF(A1, B1, “m”)

And to calculate the number of years between the same two dates, you would use the following formula:

=DATEDIF(A1, B1, “y”)
