Common questions
How many working days does 2025 have in United Kingdom?
253 — 261 Mon–Fri weekdays minus 8 national holidays that land on a weekday. Regional and local holidays sit outside the national set and would lower the number further where they apply.
How many working days is that per month, on average?
About 21.1 per month — but the spread matters more than the average: 65 working days in Q3 against 61 in Q2. A plan that assumes a flat month overcommits exactly where the calendar is thinnest.
Does this include vacation or booked time off?
No — this is the ceiling the calendar sets before anyone books leave. A team’s real capacity subtracts each person’s time off and part-time arrangement from these days; that is what the capacity calculator computes for a whole team, per member country.
Rule source: Banking and Financial Dealings Act 1971, rules last verified 2026-08-03. England and Wales bank holidays. Scotland (2 January, the first Monday in August, St Andrew's Day) and Northern Ireland (St Patrick's Day, the Battle of the Boyne) differ, and Easter Monday is not a bank holiday in Scotland. One-off royal bank holidays cannot be derived from a rule and are excluded.
Now subtract your actual team
253 days is the calendar’s ceiling for one person in United Kingdom. A real team spans countries, books leave, and works part-time — the calculator does that arithmetic for your headcount in seconds, no account.
