Frequently asked questions

Are the start and end date included?

Yes, both. From Monday to Friday of the same week is 5 working days.

Which bank holidays are left out?

The official list for the region you pick – England and Wales, Scotland or Northern Ireland – including substitute days when a holiday falls on a weekend.

Can I count working days for notice periods or deadlines?

You can count them here, but whether a deadline runs in working days or calendar days, and whether the first day counts, depends on the contract or the rule behind it. Check that first.
