For most Americans, daylight saving time ends in 2010 at 2 a.m. on Sunday, November 7, when most states fall back to standard time. Time will spring forward again on March 13, 2011, when daylight saving time resumes.

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 turn back their clocks this weekend.

While most of us plan to embrace that blessed hour (by sleeping right through it), the time change can throw a few people for a loop.

To avoid having your body clock disrupted, even if you can’t sleep an extra hour, stay in bed with your eyes closed. If you want to get up, don’t go outdoors. Draw the blinds and don’t have lots of sunlight come into house. This could help your body adjust to the time change.
