how to calculate the number of days between two dates in excel

The easiest way to calculate the number of days between two dates in Excel is to use a subtraction formula or a DATEDIF function. 1.

Use the DATEDIF function: Enter =DATEDIF(A1,B1,"d") to get the full number of days, or can also be replaced with "m" or "y" to calculate the number of months or years; 3. Pay attention to common problems: If the end date is earlier than the start date, the subtraction will return a negative number and DATEDIF will report an error, ensure that the date is correctly formatted, and check whether the imported date is in text format.
