Working Days Calculator

Yes — the count is inclusive of both endpoints. Mon to Fri (same week) gives 5 working days. If you want 'days between' (exclusive of one endpoint), subtract 1 — or use the Days Between Dates Calculator, which uses the exclusive convention.

No — you need to paste them in. UK bank holidays vary by year (the May spring bank holiday moves) and by country (England + Wales, Scotland, and Northern Ireland have different lists). gov.uk publishes the official lists; copy the dates you need into the calculator.

Monday to Friday in this calculator. Some industries (retail, hospitality, healthcare) work weekends and use different definitions; for a 6-day or 7-day working week, this calculator under-counts. The 'standard' 5-day Mon–Fri convention covers most office and professional work.

If you paste a holiday date that falls on a weekend, the calculator doesn't count it again — it's already excluded as a weekend day. Many bank holidays don't move when they fall on weekends (Christmas Day on a Saturday is still 25 December), but the working-day impact is zero. Some bank holidays do shift to the next Monday (substitute days), in which case paste the substitute date.

Possibly — but UK contracts typically express notice in calendar weeks/months, not working days. Read your contract carefully; if it says '30 days' or '4 weeks', that's calendar time. Statute or contract sometimes uses 'working days' for shorter notice (e.g. probation termination). When in doubt, ACAS or your union has guidance.

For an approximate count, yes. UK court rules (CPR for civil; Crim PR for criminal) have specific definitions of 'working day' that may include or exclude bank holidays differently. For binding legal deadlines, consult the relevant rule or a solicitor; this calculator gives the conventional Mon–Fri count.
