First the good news: Most Americans get an extra hour of sunlight every evening just as spring begins to bloom. The bad news? They lose an hour's sleep this weekend.
It's time to push the clock forward by 60 minutes during the wee hours of Sunday _ at 2 a.m. local time, officially _ to mark the arrival of daylight saving time and, unofficially, an end to winter.
The time change is not observed by Hawaii, most of Arizona, American Samoa, Guam, Puerto Rico or the Virgin Islands.
Daylight saving time ends Nov. 6.
