About this tool
Calculate the time between two dates in years, months, days, weeks and working days (Monday to Friday, French public holidays excluded, Alsace-Moselle option), find the date you get by adding or subtracting a number of calendar or working days (legal deadlines, deliveries, notice periods), and look up the public holidays of any year.
How to use this tool
- 1Enter both dates (the end date is included in the working-day count).
- 2Choose whether public holidays are excluded.
- 3Read the duration, the working days and the holidays counted.
Limits to know
- Working days = Monday to Friday. Six-day "workable days" (Monday to Saturday) are not offered.
- National statutory public holidays only (plus Alsace-Moselle as an option); bridge days, local festivals and collective agreements are not taken into account.
- Durations in months follow the calendar (January 31 + 1 month = February 28 or 29).
- Files
- No file to import: everything happens on the page.
