Working Days Calculator
Count working days (Monday to Friday) between two dates — with optional public-holiday exclusion.
From 2026-01-05 to 2026-01-30 (inclusive) there are 20 working days — 6 weekend days, out of 26 total.
Results update as you type. Both endpoints are included in the count: Mon to Fri (same week) is 5 working days, not 4. Weekend = Saturday + Sunday; if your jurisdiction treats Friday + Saturday as the weekend, the count needs adjusting.
Formula
The calculator iterates each day in the inclusive range, counts weekdays (Mon–Fri), skips Saturday and Sunday, and subtracts any holiday dates you've listed. Both endpoints are counted: Mon to Fri (same week) is 5 working days, not 4. Weekend "holidays" are ignored — they're already excluded as weekend days.

Frequently asked questions
Both endpoints included?▾
Yes — Mon to Fri (same week) gives 5 working days. If you want the exclusive count (Mon to Fri = 4), use the Days Between Dates Calculator or subtract 1.
Are public holidays automatically excluded?▾
No — paste them in. Public holidays vary substantially across EU member states. France has 11 jours fériés; Germany 9–13 Feiertage depending on the federal state; the Netherlands ~10. Religious holidays (Orthodox Easter, Eid al-Fitr) vary across years and member states.
Is the EU working week always Mon–Fri?▾
In most member states yes for office/professional work, though some sectors and southern European countries have historically had Saturday-morning working patterns. The EU Working Time Directive defines the average working week as 48 hours (over a 17-week reference period) but doesn't prescribe which days. Mon–Fri is the modern default.
Why are weekend 'holidays' ignored?▾
If a public holiday falls on a Saturday or Sunday, it's already counted as a weekend day — the calculator doesn't double-exclude. Some EU countries roll a weekend holiday to the next Monday as a substitute day (Spain often does this for some holidays); if your country does and you want the substitute counted, paste the Monday date instead.
Are EU procurement deadlines based on working days?▾
Some are; many are calendar days. The EU Procurement Directives use a mix — the standard procedure has minimum tender-receipt periods in calendar days, but some specific shifts are working-day based. Read the relevant directive or your national implementing legislation; this calculator handles the conventional Mon–Fri count.
Can I use this for paid leave / vacation planning?▾
Yes — for counting how many working days a vacation block covers. EU statutory minimum vacation is 4 weeks (Working Time Directive); most member states grant 5–6 weeks. Check whether your country and contract count vacation in working days (typical) or calendar days.
