About the calculator

A straightforward way to count time.

Days Between answers one everyday question: how many calendar days separate two dates?

What is counted

By default, the calculator measures the elapsed days from the start date to the end date. For example, January 1 to January 2 is one day. Select Include the end date when you need an inclusive count for schedules, bookings, or calendar ranges.

If the end date comes first, the calculator still returns the size of the interval. The order of the dates does not change the number of days between them.

Built for real calendars

The calculation uses calendar dates rather than local hours, so daylight-saving changes do not turn a day into 23 or 25 hours. Leap days, including February 29, are included naturally.

No account needed

There is nothing to install and no profile to create. Choose your dates, get an answer, and close the page when you are done.
