Working-day questions
Are both dates counted?
The start date always counts when it is a working day. The end date is included by default; uncheck “Include end date” to stop the count the day before.
Which French holidays are included?
The 11 national public holidays are calculated locally: New Year, Easter Monday, Labour Day, Victory in Europe Day, Ascension, Whit Monday, Bastille Day, Assumption, All Saints’ Day, Armistice Day and Christmas. Local Alsace-Moselle holidays are not included.
What if a holiday falls on a weekend?
It is counted only once. When weekends are excluded, a Saturday or Sunday holiday appears in the weekend total rather than being subtracted a second time.
Is my data sent anywhere?
No. The calculation runs entirely in your browser and no account, upload or external service is involved.
