DAYLIGHT SAVING TIME
The official phrase is Daylight Saving Time, not Daylight SavingS Time.
Saving is used in this case as a participle; it modifies time, not daylight.
But... many people feel the word savings is easier to say so Daylight Savings Time is also in common usage. It's listed in dictionaries also.

Spring forward, Fall back!
During DST, clocks are turned forward an hour, effectively moving an hour of daylight from the morning to the evening.

When do we change our clocks?
Daylight Saving Time begins for most of the United States at 2 a.m. on the first Sunday of April. Time reverts to standard time at 2 a.m. on the last Sunday of October. In the U.S., each time zone switches at a different time.

In the European Union, Summer Time begins and ends at 1 am Universal Time (Greenwich Mean Time). It starts the last Sunday in March, and ends the last Sunday in October. In the EU, all time zones change at the same moment.
