SAN FRANCISCO (CBS SF / AP) – As if you weren’t already sleep deprived, you’ll get an hour less shut-eye Saturday night into Sunday morning, no matter what time you turn out the lights.
At 2 a.m. local time Sunday, Daylight Saving Time, that harbinger of spring, arrives with the promise of longer, light-filled days well into the evening.
Turn that clock ahead – remember, “spring forward” – before heading to bed Saturday night to avoid the panic of rising later than you think.
Despite being mentioned by Ben Franklin in the 1700s, daylight saving time did not begin until World War I. The country adopted the system to conserve fuel needed to produce electric power, and has evolved it by sliding the dates around ever since. During the energy crisis in 1974, daylight saving time began in mid-winter rather than early spring.
Not every place makes the switch, though. Hawaii, Arizona outside the Navajo Indian territories, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas stay on standard time, which returns for the rest of the nation in November 2nd.
Daylight saving also serves as a reminder to check and replace batteries in smoke and carbon monoxide detectors.
