CLOCKS go back an hour tonight (Saturday) as 2012 British Summer Time comes to an end in the UK.
When the clocks change
* In spring, the clocks go forward, losing an hour – at 1am GMT the UK moves to 2am BST.
* In autumn, the clocks fall back, giving an extra hour – at 2am BST the UK moves to 1am GMT.
So when do the clocks change?
British Summer Time (BST) officially ends at 2am on Sunday, October 28, when clocks fall back 60 minutes.
Clocks should be put back an hour to 1am as the UK reverts to Greenwich Mean Time (GMT).
This means gaining an extra hour in bed on Sunday morning.
The switch also provides more daylight in the morning but makes the nights darker earlier.
BST traditionally starts on the last Sunday in March and ends on the final Sunday in October.
And when do the clocks go forward and back in 2013?
BST will start next year on Sunday, March 31 and clocks will go back again on Sunday, October 27, 2013.
The daylight saving time dates for 2014 are March 30 and October 26.
