time system under which time is advanced by one hour with respect to the standard time
Many countries have instituted a clock change over the summer months to save energy. By moving sunset closer to the time when most people go to bed, an hour's worth of electricity for lighting can be conserved. In the U.S., except for Arizona, Hawaii and part of Indiana, daylight saving time begins at 2:00 AM on the first Sunday of April, and ends at 2:00 AM on the last Sunday of October. See Saving Time, Saving Energy by the California Energy Commission for further information. Click here for a list of sites with more daylight saving time information.
The adjustment to clock time that is put into effect during the summer to extend daylight one hour later into the evening. In most locations in the United States and Canada, Daylight Saving Time begins on the first Sunday in April, when the clocks are set ahead one hour; and ends on the last Sunday in October, when the clocks are set back. Other countries change on different dates. Daylight Saving Time is one hour ahead of the equivalent standard time—6:00 P.M., for example, becomes 7:00 P.M. when Daylight Saving Time is in effect.
Daylight Saving Time (DST) or Summer Time as it is called in many countries, is a way of getting more daylight out of the summer days by advancing the clocks by one hour during the summer. Then, the sun will appear to rise one hour later in the morning when people are usually asleep anyway, at the benefit of one hour longer evenings when awake. The sunset and sunrise are one hour later than during normal time
The practice of advaning the clock one hour in the spring of the year. Significant in the erection of natal charts as it requires that one hour be subjected from the standard time when daylight saving time is in effect.
Daylight saving time (DST), also known as summer time, is a conventional local time adopted by many countries of the world on a seasonal basis. Most commonly DST is obtained by adjusting the official local time forward, by one hour, for the spring, summer, and early autumn periods.
