Have we always had Daylight Saving Time?
In the United States, Daylight Saving Time was first begun on March 31, 1918, during World War I. This plan provided more light for the evening hours, thereby saving fuel for the war effort. Since then, Daylight Saving Time has been used on and off, with different start and end dates. Currently, Daylight Saving Time begins at 2:00 A.M. on the second Sunday of March and ends at 2:00 A.M. on the first Sunday in November.
