Working Days Calculator

Pick a start and end date, tick the days of the week you work, choose your UK region for bank holidays, and decide whether to exclude them. The working-days count updates instantly. The range is inclusive — both the start and end dates count if they’re working days for you.

Worked example: a full-time Monday–Friday worker in England & Wales counting 1 January to 31 December 2026 with bank holidays excluded gets 253 working days. There are 261 weekdays in 2026, and eight bank holidays fall on weekdays, leaving 253.

The calculator walks through every day in your date range (inclusive) and counts only the weekdays you’ve ticked as working days. With bank holidays switched on, any bank holiday that falls on one of your working days is removed from the count and listed in your results.

Bank holidays use the official GOV.UK calendars for 2025, 2026 and 2027. England & Wales typically has eight bank holidays a year; Scotland has nine or ten (including the 2nd of January and St Andrew’s Day, but no Easter Monday); Northern Ireland has ten (including St Patrick’s Day and the Battle of the Boyne).

The three UK nations do not share the same bank holiday calendar, so the same date range can give a different working-day total depending on where you work. Choosing the right region keeps your count accurate.

England & Wales: eight holidays — New Year’s Day, Good Friday, Easter Monday, the Early May and Spring bank holidays, the Summer bank holiday (last Monday in August), Christmas Day and Boxing Day. When Christmas or Boxing Day falls on a weekend, a substitute weekday is given instead (for example, in 2026 Boxing Day falls on a Saturday and is observed on Monday 28 December).

Scotland: nine or ten holidays — New Year’s Day and the 2nd of January, Good Friday, the Early May and Spring bank holidays, the Summer bank holiday (first Monday in August), St Andrew’s Day (30 November, or the nearest substitute weekday), Christmas Day and Boxing Day. Scotland does not observe Easter Monday as a bank holiday. In 2026 an additional World Cup bank holiday falls on 15 June.

Northern Ireland: ten holidays — the same eight as England & Wales plus St Patrick’s Day (17 March, or the nearest substitute weekday) and the Battle of the Boyne / Orangemen’s Day (12 July, or the nearest substitute weekday). In 2025 St Patrick’s Day falls on a Monday and the Battle of the Boyne is observed on Monday 14 July; in 2026 the Battle of the Boyne is observed on Monday 13 July.

Practical effect: a full-time Monday–Friday worker in 2026 has about 253 working days in England & Wales, but around 251 in Scotland and Northern Ireland, because those nations have two extra bank holidays that fall on weekdays.

Full-time, England & Wales, all of 2026: 261 weekdays minus 8 bank holidays on weekdays = 253 working days (with bank holidays excluded). With bank holidays included the figure is 261.

Part-time, Monday/Wednesday/Friday, England & Wales, all of 2026: 156 Mon/Wed/Fri days minus 7 bank holidays that fall on those days = 149 working days. One 2026 bank holiday (Boxing Day, observed Monday 28 December) falls on a non-working day for this pattern, so it is not subtracted.

Full-time, Scotland, all of 2026: 261 weekdays minus 10 bank holidays on weekdays = 251 working days. The extra holidays are the 2nd of January, St Andrew’s Day and the 15 June World Cup bank holiday, offset by the absence of Easter Monday.

Full-time, Northern Ireland, all of 2026: 261 weekdays minus 10 bank holidays on weekdays = 251 working days. The extra holidays are St Patrick’s Day (17 March) and the Battle of the Boyne (observed Monday 13 July).

A full-time Monday–Friday worker in England & Wales has around 253 working days in 2026 once the eight bank holidays are excluded. Part-time workers can untick the days they don’t work to get their own figure — useful for checking pro-rata holiday entitlement or planning projects.
