Spring forward; Fall back.
Don't forget to set your clocks(those that aren't automatic) back 1 HR tonight before going to bed.
An extra hour of cold, dark fall mornings is probably the last thing you look forward to when you first wake upor when you're driving to work, dropping off your children at school, or walking the dog. Similarly in mid-March, when we first "spring forward." So why do we suffer through this?
Supposedly, to save energy. Clever as he was, Benjamin Franklin didn't anticipate the eventual importance of air conditioning, a much more expensive item than lighting. Thanks to daylight-saving time, in the summer people come home from work an hour earlier and crank up their air conditioner in the hottest part of the day.
Profs. Matthew Kotchen of Yale University and Laura Grant of the University of Wisconsin-Milwaukee found that daylight-saving time increases energy use by over 1% in Indiana during those monthsadding some $9 million to energy bills annually, plus sending an additional 188,000 tons of carbon dioxide into the atmosphere. Daylight-saving time imposes the greatest costs in the fall, the researchers found, when it prompts increases in morning heating without any savings on lighting. But it also imposes high costs in July and August, when increased air-conditioning bills more than offset the savings in lighting.
The United States adopted the annual use of daylight-saving time permanently in 1966, then lengthened its duration on the calendar in 1986 and again in 2007. For the past five years, an extended daylight-saving period has begun the second Sunday of March and ended the first Sunday of November.
