How to use Date Difference Calculator

Choose two calendar dates. The calculator subtracts the start from the end and reports absolute day difference with a direction note.

Example

January 1 through January 31 represents 30 elapsed days, excluding the starting day.

What to know

If your task counts both start and end dates, add one. This is a calendar-day count and does not represent elapsed hours across time-zone changes.
