Calculate the exact time between two dates: years, months, and days, plus total days, weeks, hours, business days, and months.
Everything runs locally in your browser — nothing is sent to a server.
No. The difference is calculated from the start of the first date to the start of the second, which is the standard convention. For example, January 1 to January 2 is a difference of 1 day.
Business days count only Mondays through Fridays, excluding weekends. Public holidays are not excluded because they vary by country and region.
The order doesn't matter — the tool automatically uses the earlier date as the start. The result is always a positive duration.
