Date calculator

Calendar or business-day gaps (France holidays optional) and deadlines by adding days to a date.

Difference between two dates

Deadline: add days to a date

Day type

How it works

  1. Dates use your local calendar (no forced timezone).
  2. Business days are Monday–Friday; with holidays enabled, French public holidays are skipped too (including Easter Monday, Ascension, Whit Monday).
  3. Calendar gap is end − start in whole midnights, like a plain date subtraction.
