Why Is There Daylight-saving Time?
Daylight-saving time is the practice of advancing clocks during summer months by one hour so that in the evening daylight is experienced an hour longer, while sacrificing normal sunrise times.
Daylight-saving time enhances our enjoyment of the summer by giving us extra daylight after work for recreation and other summertime activities.
Daylight-saving time begins on the last Sunday in April and ends six months later on the last Sunday in October. During this period, clocks in most parts of the United States are set one hour ahead of standard time.
As a result, an hour of daylight has been “saved” at the end of a day. We do not have daylight-saving time during the winter because daylight time is shorter, and not so much daylight can be saved.
