Daylight Savings Time in 2015 began on Sunday, March 8 at 2 a.m., at which time the clocks in areas that observe it were set ahead one hour. Daylight Savings Time ends on Sunday, November 1 at 2 a.m. when the clocks in these jurisdictions are turned back one hour.
Daylight Savings Time has the effect of moving an hour of daylight from the morning to the evening but makes the days seems shorter to many people when it ends. For most of the United States, Daylight Savings Time begins on the second Sunday in March and ends on the first Sunday of November. The European Union uses a similar device called Summer Time, which begins and ends in all time zones at 1 a.m. Universal or Greenwich Mean Time. It begins on the last Sunday in March and ends on the last Sunday in November.
