Daylight Saving Time
? Daylight Saving Time, system of setting clocks 1 hour ahead so that both sunrise and sunset occur at a later hour, producing an additional period of daylight in the evening. Daylight saving has been used in the United States and in many European countries since World War I, when the system was adopted in order to conserve fuel needed to produce electric power. During World War II the U.S. Congress passed a law putting the entire country on “war time,” which set clocks 1 hour ahead of standard time for the duration of the war. Under one legislation enacted in 1986, daylight saving time begins at 2 am on the first Sunday of April and ends at 2 am on the last Sunday of October.
