Fall Back! Daylight Saving Time for 2012 Ends Sunday
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. and 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 evening hours.
Europe set its clocks back one hour to Winter Time last Sunday at 1 a.m. GMT.
For 2013, Daylight Saving Time will start on March 10 in most of North America; in the European Union, Summer Time will start on March 31, leaving the U.S. out of sync with a good part of the world for over two weeks.
Most of Asia, Africa, and South America do not observe Daylight Saving Time at all.
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.
