Count werkdagen / jours ouvrables in Belgium between two dates, or add working days to a date, without weekends and the 10 legal public holidays.
Because replacement days for holidays on a Sunday are chosen by each employer, they aren’t added automatically — enter yours as an extra day off. The community holidays (11 July, 27 September, 15 November) are listed for their community but are working days for most private employers.
Working days in a whole year, Monday to Friday with public holidays removed — 2026: 253 in Belgium · 2027: 254 in Belgium.
Step by step
- Choose Belgium and your community: Belgium is preselected; pick the community whose holidays apply where you work.
- Enter the dates: For a count, pick the start and end dates and choose whether the end date counts. To find a deadline, switch to Add or subtract days and enter the number of working days.
- Set your week: Choose the weekend days (Saturday and Sunday by default) and type any extra days off — local holidays, a shutdown, leave — one per line.
- Check the holidays used: Under the result, every public holiday in the range is listed with whether it was a day off, on a weekend or counted as a working day.

Questions
How do I count a six-day working week?
Some Belgian rules on leave and notice count Monday to Saturday as working days. Set the weekend to Sunday only to get that count.
How many working days are there in a year in Belgium?
Counting Monday to Friday and removing public holidays — 2026: 253 in Belgium · 2027: 254 in Belgium. Extra days off you add come on top.
Is the start date counted?
When counting between two dates, the start date is always included and the end date only if “Include the end date” is ticked. When adding working days, the start date itself is not counted.
Is anything sent to a server?
No. The holiday rules and every calculation run in your browser, and the PDF, calendar file and CSV are made on your device. Nothing you type — dates, extra days off — leaves it.
