DST (daylight saving time) is when local standard times are turned forward 1 hour. It’s also called Spring Forward and Summer Time. This year, it will happen on Sunday, March 11, 2018. This will change the time from 2:00am to 3:00 am local daylight time instead. The purpose of this is to save energy and to have more daylight in the evening, so that people could take advantage of the extra evening daylight rather than wasting energy on lighting.
DST will end on November 4, 2018, and the clock will get turned backward 1 hour, from 2:00 am to 1:00 am local standard time, this is also called winter time and Fall Back.
Arizona and Hawaii are the only two states in USA that doesn’t use DST. It is now used in over 70 countries worldwide and affects over 1 billion people every year. The countries that follow DST includes: United Kingdom, Canada (Charlie Lake, Creston , Dawson Creek, Fort St. John, and Taylor), Saskatchewan (Creighton and Denare Beach), Australia (Canberra, New South Wales, Victoria, South Australia, Tasmania ), New Zealand, South America, southern Africa, Russia, Albania, Austria, Belgium, Brazil, Chile, Greenwood, Mexico, Morocco, Netherland, etc.
New Zealand scientist, George Vernon Hudson and British builder William Willett was the first to invented DST. In 1895, Hudson presented a paper to Wellington Philosophical Society, proposing a 2-hour shift forward in October and a 2-hour shift backward in March. There was interest in the idea, but it was never followed through. In 1905, Hudson and Willett suggested setting the clocks ahead 20 minutes on each of the 4 Sundays in April, and switching them back by the same amount on each of the 4 Sundays in
September, a total of 8 time switches per year.
While Germany and Austria were the first countries to use DST in 1916 as a way to conserve fuel during the first World War. The rest of Europe began to use it shortly after. However, it is a little-known fact that a few hundred Canadians beat the German Empire by 8 years. On July 1, 1908, Port Arthur, Ontario, today's Thunder Bay, turned their clocks forward by 1 hour to start the world's first DST period. In 1918, the United States adopted daylight saving time. But it was abolished until the second World War on February 9,1942, when President Franklin
Roosevelt re-established DST year-round, calling it “War Time”.
In 2007, the Energy Policy Act of 2005 went into effect, expanding the length of DST.
