Day Light saving, A usual trick used by governments to increase the amount of daylight in a country by varying the time zones for a particular intervals with which most of us are unaware about.
They change their clocks twice in a year in order to create longer summer evenings.
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. Universal Time (Greenwich Mean Time). It begins the last Sunday in March and ends the last Sunday in October. In the EU, all time zones change at the same moment.
