About Working Days UK

Working Days UK is a free tool for one job: working out UK working days. Most date calculators are built for the US or for everywhere at once, so UK users end up typing in bank holidays by hand. This site is built for the UK only, with the right bank holidays for England and Wales, Scotland and Northern Ireland already included.

Where the dates come from

Bank holiday dates come from the official GOV.UK bank holidays list, which currently covers 2019 to 2028. The list was last checked on23 September 2026. For later years we use the standard rules and say so on the result. One-off holidays are added when the government announces them.

How it works

All calculations run in your browser. The dates you enter are not sent to our servers, and you don’t need an account. The site is paid for by advertising. See our terms and privacy policy.
