Daylight Savings Time 2011 is proposed to take maximum utilization of sunny daytime in summer. The clocks will move an hour backwards in winter, because winter days will be darker than summer days.
A report published in 2008 by the U.S. Department of Energy revealed that 4 weeks of daylight savings time could conserve 1.3 trillion watt-hours per day, enough to power 100,000 homes for a year. However, not all agree to this saving and neither does the principle run good in all geographical areas.
Benjamin Franklin thought of saving time thus in 1784, but the idea was put into practice only during World War I to conserve energy.
Usually, Daylight Saving Time begins before the arrival of summer in March or April and ends with the dawn of winter in September or October in the United States. The practice has been followed by most of states in the U.S. except a few like Alaska and Hawaii.
However, many question Daylight Saving Time system. Several people claim that it is a meaningless custom and needs not to be followed in the modern era. People in fact feel it hard to change time on each clock in their houses twice a year. Computers and smartphones clocks may automatically recognize the change.
Many people have sent messages to their representatives so as to force the congress to get rid of the DST system.
However, Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas do not observe DST because, “”According to an Arizona Republic editorial from 1969, the reason was the state’s extreme heat. If Arizona were to observe Daylight Saving Time, the sun would stay out until 9 p.m. in the summer (instead of 8 p.m., like it does currently).”
