Get ready to "spring forward" and give up an extra hour of sleep-- daylight savings time will officially take place this weekend.
At 2 a.m. local time, Sunday, all but two states-- Arizona and Hawaii --will observe the change. It will mean trading one hour of sleep for more evening sunshine.
Bill Mosley, a public affairs officer at the U.S. Department of Transportation, said research has shown that more available daylight decreases the number of traffic accidents, traffic fatalities and incidences of crime.
"[Daylight savings is] to adjust daylight hours to when most people are awake and about," he explained.
The shift also serves as a reminder to install new batteries in warning devices such as smoke detectors and hazard warning radios.
This is the third year daylight saving time occurs on the second Sunday in March, rather than the first Sunday in April.
A federal law signed in 2005 extends daylight saving time by one month, reportedly to save more energy. The time adjustment originally began during World War I with the same intention.
In areas that observe the change, standard time will return on Nov. 1.
