Frequently asked questions

Do the calculators include bank holidays?

Yes. The working days calculator lets you choose England and Wales, Scotland or Northern Ireland and removes that nation’s bank holidays.

Is the end date counted?

Each tool explains how it treats the start and end dates, so read the note under the result when an exact count matters.

Which time zone is used?

Dates use the UK calendar, and time tools do not need a time zone because they work with durations.

Are these dates official?

They follow published GOV.UK dates, but always check official guidance for legal or immigration deadlines.
