Mark Your Calendars: Daylight Savings Time

Daylight Savings Time Begins on March 13, 2011 at 2:00 a.m. with a "Spring Forward" motion on the clock to 3:00 a.m.

Daylight Saving Time (or summertime as it is called in many countries) is a way of getting more light out of the day by advancing clocks by one hour during the summer. 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.

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 activies.

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. However, many studies disagree about the energy savings of DST and while some may show a positive outcome of the energy savings, others do not.

It is difficult to predict what will happen with Daylight Saving Time in the future. The daylight saving date in many countries may change from time to time due to special events or conditions.The United States, Canada and some other countries extended DST in 2007. The new start date is the second Sunday in March (previously the first Sunday in April) through to the first Sunday in November (previously the last Sunday in October).

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.
