Calculateur d'écart de dates

Calculez le nombre exact de jours, semaines, mois et années entre deux dates.

Total days

30

Weeks4 and 2 days
Months1 and 0 days
Years0 and 30 days

Comment utiliser

  1. Pick a start date and an end date, in either order.
  2. The total days and the week, month and year breakdowns appear immediately.
  3. Turn on Include both endpoints to count both the first and the last day (+1).

Remarques

All math is done on UTC calendar days, so time zones and daylight saving never change the result. Month arithmetic follows the calendar and clamps to the last day of the target month (for example, one month after Jan 31 is Feb 28).

Questions fréquentes

Why do identical dates give 0 days?
The tool measures the gap between the two dates. If you want to count both days themselves, turn on Include both endpoints and the same pair gives 1 day.
