Also known as DST, summer time, daylight savings time, daylight time
Daylight saving time (DST), also referred to as daylight savings time, daylight time, or summer time, is the practice of advancing clocks to make better use of the longer daylight available during summer by having darkness fall at a later clock time. The typical implementation of DST is to adjust clocks ahead of standard time by one hour in spring or late winter, and to set clocks back by one hour in the autumn.
Daylight saving time is the practice of moving clocks forward by one hour in spring to take advantage of longer daylight hours during summer, so that it stays light later into the evening. In the fall, clocks are moved back by one hour to return to standard time.
