Clocks go back one hour this Sunday, 29 October
Remember, clocks go back on hour this Sunday as British Summertime comes to an end.
In the UK the clocks go forward one hour at 1am on the last Sunday in March, and back one hour at 2am on the last Sunday in October.
The period when the clocks are one hour ahead is called British Summer Time (BST). There's more daylight in the evenings and less in the mornings (sometimes called Daylight Saving Time).
When the clocks go back, the UK is on Greenwich Mean Time (GMT).
We'll be putting them forward an hour on March 25, 2018.
