Daylight Saving Time 2011: Why and When Does It End?
Why fall back? Should daylight savings be stopped? Get the facts.
For most Americans, daylight saving time 2011 ends at 2 a.m. on Sunday, November 6, 2011, when most states fall back an hour. Time will spring forward to daylight saving time again on Sunday, March 11, 2012, when daylight saving time begins again.
The federal government doesn't require U.S. states or territories to observe daylight saving time, which is why residents of Arizona, Hawaii, Puerto Rico, the Virgin Islands, American Samoa, Guam, and the Northern Marianas Islands won't need to change their clocks this weekend.
Where it is observed, daylight savings has been known to cause some problems.
National surveys by Rasmussen Reports, for example, show that 83 percent of respondents knew when to move their clocks ahead in spring
