Daylight Saving Time (DST) in the United States and Canada ends on Sunday, Nov. 3, at 2 a.m., so when you go to bed Saturday night on Nov. 2, 2013, you can set your clock back and look forward to getting an extra hour of sleep. While some people try to remember the “fall back” and “spring forward” trick to remember whether to set the clock forward or back when Daylight Saving Time ends, an alternative way to remember to set one’s clock back is to remember that winter time means more sleep. According to an Oct. 26, 2013, Latin Times report, “the reasoning behind daylight savings and the time shifts was to take advantage of the daylight in the mornings and the lighter evenings during the summer.”
Since 2007, Daylight Saving Time starts on the second Sunday of March and ends on the first Sunday of November, with all time changes taking place at 2 a.m. local time.
In 2012, Daylight Saving Time began on March 11 and ended on Nov. 4, 2012. This year, Daylight Saving Time began on March 10 and will end on Nov. 3, 2013. For 2014, the scheduled Daylight Saving Time is planned for March 9 until the end of Daylight Saving Time on Nov. 2, 2014.
Historically, Daylight Saving Time in the United States dates back to the Standard Time Act of 1918, which was the first United States federal law implementing standard time and Daylight Saving Time in the United States. While the intent of Daylight Saving Time was to save energy by taking advantage of longer daylight, that intent was not easily accepted throughout the years and throughout all of the states.
After the end of World War I, Congress abolished the idea of saving energy with Daylight Saving Time, but with the beginning of World War II, “President Franklin D. Roosevelt instituted year-round DST in the United States, called ‘War Time’ during World War II from February 9, 1942 to September 30, 1945. The law was enforced 40 days after the bombing of Pearl Harbor and during this time, time zones were called ‘Eastern War Time’, ‘Central War Time’, and ‘Pacific War Time’. After the surrender of Japan in mid-August 1945, the time zones were relabeled ‘Peace Time’.”
According to a report by timeanddate.com, Daylight Saving Time (DST) “caused widespread confusion from 1945 to 1966 for trains, buses and the broadcasting industry in the US because many states and localities were free to choose when and if they would observe DST.”
To end the confusion, Congress established the Uniform Time Act of 1966 which stated that Daylight Saving Time should begin on the last Sunday of April and end on the last Sunday of October.
Following the Uniform Time Act of 1966, Daylight Saving Time in the United States was revised several times over the years. From 1987 to 2006, Daylight Saving Time lasted for seven months. Since 2007, the Daylight Saving Time schedule is following the Energy Policy Act of 2005, which extended the period by about one month where DST starts on the second Sunday in March and ends on the first Sunday in November.
Presently, most states are implementing Daylight Saving Time and thus are ending Daylight Saving Time on Nov. 3 at 2 a.m. As of 2012, Arizona, Hawaii, American Samoa, Puerto Rico, and the Virgin Islands are not following Daylight Saving Time – so no extra hour of sleep in any of those states.
