This occurs the second Sunday in March and that means clocks will advance at 2 a.m. Sunday, March 13, 2011!
So, prepare to lose one hour of sleep or late-night entertainment as you forcibly spring forward.During Daylight Saving Time, the sun appears to rise one hour later in the morning, when people are usually asleep anyway, and sets one hour later in the evening, seeming to stretch the day longer.
Daylight saving time begins in the northern hemisphere between March–April and ends between September–November. Standard time begins in the northern hemisphere between September–November and ends between March–April. Many countries in the northern hemisphere may observe DST.
Daylight saving time begins in the southern hemisphere between September–November and ends between March–April. Standard time begins in the southern hemisphere between March–April and ends between September–November. Many countries in the southern hemisphere may observe DST.
Why Observe DST?
Many countries observe DST, and many do not. The reason many countries implement DST is in hopes to make better use of the daylight in the evenings, as well as some believe that it could be linked to reducing the amount of road accidents and injuries. The extra hour of daylight in the evening is said to give children more social time with friends and family and can even boost the tourism industry because it increases the amount of outdoor activities.
DST is also considered as a means to save energy due to less artificial light needed during the evening hours—clocks are set one hour ahead during the spring, and one hour back to standard time in the autumn.
Brief History of Daylight Savings Time
Benjamin Franklin first suggested Daylight Saving Time in 1784, but modern DST was not proposed until 1895 when an entomologist from New Zealand, George Vernon Hudson, presented a proposal for a two-hour daylight saving shift to the Wellington Philosophical Society.
The conception of DST was mainly credited to an English builder, William Willett in 1905, when he presented the idea to advance the clock during the summer months. His proposal was published two years later and introduced to the House of Commons in February 1908. The first Daylight Saving Bill was examined by a select committee but was never made into a law. It wasn’t until World War I, in 1916, that DST was adopted and implemented by several countries in Europe who initially rejected the idea.
