Daylight savings time (DST) is the annual adjusting of the clocks in the warmer months of the year so that workers can enjoy increased daylight in the afternoon and evening. It has always been controversial as although it is advantageous for retailers, sports organisers and other activities to exploit an extra hour of daylight it can be problematical for activities tied to the sun, such as farming.
According to California's Energy Commission, Congress enacted DST as a way to conserve
When Is Daylight Savings Time and Which Direction Does the Clock Move?
Starting from 2007, day light saving time begins at 2:00 am on the second Sunday in March, and ends at 2:00 am on the first Sunday in November. The clock moves ahead in the spring which means people lose an hour of sleep as the clock is moved forward at 2:00 am standard time to 3:00 am daylight saving time. At the end of DST people get an extra hour of sleep as the clock is moved back an hour.
The phrases "spring forward, fall back" or "spring ahead, fall behind" are an easy way to remember which way to turn the clocks. Changing the clocks is always carried out on a Sunday to minimize disruption and in practice on the Saturday night before the start of daylight savings time, clocks should be set forward one hour before going to bed. On the night before the end of daylight savings time, clocks should be set back one hour to return to standard time.
