Worked example
Say you're working out a notice period from 3 March to 17 April 2026. That's 45 calendar days. But if you only count working days — excluding weekends and the Good Friday and Easter Monday bank holidays that fall in that window — it comes to 30 working days. That's the kind of gap that trips people up when a contract says "30 days" without specifying which kind.
What counts as a working day in the UK?
A working day in the UK is any day that is not a Saturday, Sunday or a public bank holiday. For most employees this means Monday to Friday excluding bank holidays, giving a typical year of around 252 working days. Some contracts or industries define working days differently — always check your contract if you need a precise legal interpretation.
Common questions
Does this use UK bank holidays for all of the UK, or just England and Wales?
England and Wales bank holidays by default — Scotland and Northern Ireland have some different dates, so working day counts will vary slightly if you're in either.
Why would a business quote "working days" instead of just days?
It protects them from weekends and holidays extending a deadline unexpectedly — common in delivery estimates, notice periods, and contract terms.
What's the difference between this and the days-between-dates calculator?
This one strips out weekends and bank holidays automatically; the days-between-dates tool gives you all the versions (calendar, working, weeks, months) side by side.
