When we change our clocks. Most of the United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November. In the U.S., each time zone switches at a different time. In the European Union, Summer Time begins and ends at 1:00 a.m.
British Summer Time will officially end later this month. Clocks in Britain will go back by one hour on Sunday, 30 October, bringing an end to Daylight Saving Time, otherwise known as British Summer Time. The clocks change at 2am on the last Sunday of October, meaning there is less daylight in the evenings and more in the mornings. During British Summer Time, where clocks were set one hour ahead from the last Sunday in March, there is more daylight in the evenings and less in the mornings.
