Le guide ci-dessous n'est pas encore disponible en français et s'affiche en anglais. Le calculateur lui-même est entièrement traduit.
Comment utiliser ce calculateur
- Choose to count business days or to add business days.
- Enter the dates (and the number of days to add, if applicable).
- Choose which days are the weekend. Some countries use Friday–Saturday.
- Optionally list public holidays as YYYY-MM-DD dates to exclude them.
Formule
Every full week contributes the same number of working days; the remaining days are checked one by one, and listed holidays that fall on working days are subtracted.
Business days = calendar days − weekend days − holidays on weekdays
Example
- Monday 2 November to Friday 13 November 2026, both included: 12 calendar days.
- Minus 2 weekend days = 10 business days.
Questions fréquentes
Are public holidays included automatically?
No. Holidays differ by country, region and employer, so you list the ones that apply. This keeps the calculation correct for any location.
Is the start date counted?
When counting, the start date is included. Tick 'include end date' to include the end date as well. When adding business days, counting starts the day after the start date.
How do I count working days with a different weekend?
Choose Friday–Saturday or Sunday only in the weekend setting.
