Clock change countdown
Days until the clocks go forward
When the clocks go forward
In the UK and Europe the clocks go forward on the last Sunday in March, when summer time begins. In the UK, 1:00 am Greenwich Mean Time becomes 2:00 am British Summer Time, so that night is an hour shorter. In the United States and most of Canada, daylight saving time begins on the second Sunday in March, when 2:00 am becomes 3:00 am.
You lose an hour of sleep but gain lighter evenings. Remember to change manual clocks, car dashboards and ovens, as phones and computers usually update themselves.
If you work nights, a shift that runs across the change is an hour shorter in spring, so check with your employer how it is paid. The shift planner can help you lay out the week.

Do I lose an hour of sleep when the clocks go forward?
Yes. On the night of the change the hour between 1:00 am and 2:00 am in the UK does not exist, so the night is an hour shorter.
