Moving the Clocks
Forward / Back one hour in the UK

Since 1972, Britain has decided to go with Greenwich Mean Time (GMT) in winter, and British Summer Time (BST) in Summer.

clockChanging the clocks

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

In the Spring, we add an hour, and go onto what is called British Summer Time.

In the Autumn (Fall), we do the reverse, and adhere to Greenwich Mean Time.

clockWhen do the clocks change in the UK?

Clocks went forward one hour on rthe last Sunday in March 01:00 GMT(02:00 BST)

Clocks moved one hour backwards on the last Sunday in October 02:00 BST(01:00 GMT )

Year Clocks go forward Clocks go back
2013 31 March 27 October
2014 30 March 26 October
2015 29 March 25 October

clock What time do the clocks change?

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

clock When is the UK on Greenwich Mean Time (GMT)?

November to the end of March

At 2 am (01:00) GMT on the last Sunday in October, clocks move back by one hour for the end of British Summer Time. (We move our clocks back one hour from 2am to 1am)

clock When is the UK on British Summer Time (BST)?

April to the end of October

At 1 am (01:00) GMT on the last Sunday in March we move our clocks forward by one hour for the start of British Summer Time.

Summer time is from the last Sunday in March until the last Sunday in October.

We can remember which way the clocks are set by the help of this phrase:

Spring Forward; Fall Back (Fall = Autumn)

clockWhy do we change our clocks?

It's all to do with saving the hours of daylight, and was started by a man called William Willett, a London builder, who lived in Petts Wood in Kent (near our school).

Basically, he reckoned that he could improve the population's health and happiness by putting forward the clocks by twenty minutes on each of four Sundays in April, and by reversing this idea by the same amount on four Sundays in September.
