Since 1972, Britain has decided to go with Greenwich Mean Time (GMT) in winter, and British Summer Time (BST) in Summer.
Changing 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
When do the clocks change in the UK?
2008 Clocks went forward one hour on Sunday 30 March 01:00 GMT* (02:00 BST) * As the UK is currently on GMT, we changed our clocks at 1 am on Sunday 30 March. |
Clocks moved one hour backwards. Sunday 26 October 02:00 BST** (01:00 GMT ) **As the UK is currently on BST (British Summer Time), we will change our clocks at 2 am on Sunday 26th October. |
Future dates 2009: the Sundays of 29 March and 25 October |
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
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)
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) |
Why 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.
