Spring Forward! 2013 Daylight Saving Time Starts This Sunday in U.S.
In the European Union, Summer Time (called British Summer Time or BST in the Untied Kingdom and Sommerzeit in Austria and Germany) will start three weeks later on March 31. This discrepancy in start times leaves the U.S. out of sync with a significant part of the world for three weeks (a few years ago, it was just one week).
Daylight Saving Time will end on November 3 and resume on March 9, 2014. In the European Union, Summer Time will end on October 27 and resume March 30, 2014.
Daylight Saving Time is a system of managing the changing amounts of daylight that occur during the year, with a goal of maximizing daylight hours during the typical workday. It was first proposed in 1784 by Benjamin Franklin, who believed it would save an “immense sum.” It was not broadly adopted until the early twentieth century when the U.S. temporarily enacted Daylight Saving Time as an energy-saving measure.
By adjusting clocks ahead by an hour, people typically have more daylight available during the workday. For example, in the case of someone who typically awakens at 7 a.m., since in the spring the sun rises earlier each day, an individual would have to rise at 6 a.m. to take advantage of the additional daylight. Instead, by moving the clock ahead by one hour, that person can continue to wake up at 7 a.m. and enjoy more daylight in the early evening hours.
Daylight Saving Time is not observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands, and Arizona (with the exception of the Navajo Nation). Until 2006, the counties in the Eastern Time Zone of Indiana did not observe Daylight Saving Time and remained on standard time year round. As of April 2006, all of Indiana observes Daylight Saving Time. Most of Asia, Africa, and South America do not observe Daylight Saving Time at all.
