Some of you will be looking to change the clocks tonight but don't it is next weekend.
The clocks will go back by one hour at 2.00 am on Sunday 30 October. Rather than 2.00 am, the clocks will go back to 1.00 am as British Summer Time ends for another year.
British Summer Time (BST) starts each year on the last Sunday in March and ends on the last Sunday in October. On Sunday 27 March the clocks will go forward, meaning we lose an hour. British Summer Time is due to end this year on 30 October.
