In the UK the clocks go forward 1 hour at 1am on the last Sunday in March, and go back by 1 hour at 2am on the last Sunday in October.
Clocks go forward
Clocks go back
The period when the clocks go forward by an hour is called British Summer Time (BST), and there is more daylight in the evenings and less in the mornings. When the clocks go back, the UK is on Greenwich Mean Time (GMT).
Which do you prefer, lighter mornings or lighter evenings?
