UK Working Days Calculator

Project timelines, notice periods, freelancers’ quotes and annual leave all care about working days — not just calendar days. Counting weekdays by hand is easy to get wrong around bank holidays.

This free UK working days calculator counts inclusive days between two dates, splits weekdays and weekends, and can exclude England & Wales bank holidays from a built-in list covering 2025–2028.

Scotland and Northern Ireland observe additional or different public holidays. Always confirm with GOV.UK or your employer’s holiday calendar for contractual purposes.

England & Wales bank holidays 2025–2028 (built-in list)

What counts as a working day?

In everyday UK office use, a working day is usually Monday to Friday, excluding public holidays. Some contracts define working days differently (for example including Saturdays in retail). This tool uses Mon–Fri and optional bank-holiday exclusion.

Counts are inclusive: from Monday to Friday in the same week is five working days if no holidays fall in between. Inclusive counting matches many business “within X working days” phrases, but always read the contract.

Bank holiday coverage

The built-in list follows common England & Wales dates for 2025–2028, including substitute days when Christmas or Boxing Day fall at the weekend. Dates can be confirmed or updated by government — check GOV.UK for the authoritative list.

Frequently asked questions

Are both start and end dates counted?

Yes. The range is inclusive. A single day selected as both start and end counts as one calendar day (and one working day if it is a weekday).

Which bank holidays are included?

A built-in England & Wales list for 2025–2028 (New Year, Easter, May holidays, August, Christmas and Boxing Day, with substitutes where relevant).

What about Scotland or Northern Ireland?

Those nations have extra or different holidays. This tool does not fully model them — verify on GOV.UK if your work follows those calendars.

Does this calculate annual leave entitlement?

No. It only counts days in a date range. Statutory leave rules depend on your contract and working pattern.
