Result: Enter two dates and calculate.

How it works

The calculator converts each date to a UTC calendar date and measures the absolute number of 24-hour days between them.

Example: October 1 to October 15 is 14 days, or exactly 2 weeks.
Important limitation

This is a calendar-day difference. It does not count both endpoint dates inclusively and does not calculate business days.
