Date Difference Calculator

Elapsed time and calendar time

Total days is the exact number of midnights between the dates. The calendar difference counts complete calendar years and months first, then the remaining days. Month lengths and leap years can make that breakdown differ from a fixed-day estimate.

Weekday and weekend totals count the days after the earlier date up to and including the later date. The dates are handled as calendar dates, so times and time zones do not affect the result.
