When do the clocks change in the UK?

In the UK, we all change our clocks and watches by one hour, twice a year.

On the last Sunday in March we add an hour and go onto what is called British Summer Time (BST).

On the last Sunday in October we put our clocks back one hour and adhere to Greenwich Mean Time (GMT).

The clocks are always changed at 01:00 GMT (02:00 BST).

In the Autumn (October), as we are on BST (British Summer Time) before the clocks change, we change the clocks at 02:00.

In the Spring (March) we are already on GMT so change the clocks at 01:00.

An easy way to remember when the clocks go forward or back is: "Spring forward, Fall back". It uses "Fall" which is the American term for Autumn but still serves as a simple reminder that the clocks 'spring forward' in the Spring and 'fall back' in the 'Fall' (Autumn).

When do other countries change their clocks?

European Union - Most countries change their clocks on the last Sundays of March and October.

North America and most of Canada change their clocks on the second Sunday in March and the first Sunday in November.
