Days Between Dates

Count the exact days, weeks and months between two dates. Great for deadlines, events and holidays.

How it works

  1. 1

    Pick the start date and the end date.

  2. 2

    Order does not matter: the tool computes the absolute difference.

  3. 3

    Read the day total and its week equivalent.

How does it work?

The difference between two dates is measured in absolute days: from the 1st to the 10th of a month there are 9 days, not 10. This calculator subtracts with the real calendar, including leap years.

Besides the day total, you get the breakdown into full weeks and leftover days, which is how we usually think about deadlines (for example, 9 days = 1 week and 2 days).

Frequently asked questions

Does it include the start and end days?

No: it computes the absolute difference. From the 1st to the 10th there are 9 days. If you need to count both ends (for holidays including first and last day), add 1 to the result.

Does the order of the dates matter?

No. If you enter the later date as the start, the tool still computes the absolute distance between both.

Does it handle leap years?

Yes. Working with real calendar dates, February 29ths are counted automatically whenever the range includes them.
