Early Sunday morning, Oklahomans will need to turn their clocks forward one hour.
The move effectively moves an hour of daylight from morning to evening.
Starting last year, daylight saving time began on the second Sunday in March and ended on the first Sunday in November.
On the second Sunday in March (March 9, 2008), clocks are set ahead one hour at 2:00 a.m. On the first Sunday in November (November 2, 2008), clocks will need to be set back one hour at 2:00 a.m.
These dates were setup by the Energy Policy Act of 2005.
Fire officials as always, are urging people to change smoke detector batteries with the changing of the clocks.
Sleep experts say the start of daylight saving time provides an ideal opportunity to examine your sleep patterns and make some changes as well.
"A one hour shift isn't cataclysmic, but it does take some acclimatizing," says Dr. Ralph Downey, chief of sleep medicine at Loma Linda University Medical Center and Children's Hospital in Loma Linda, Calif.
"I don't see the point. Our bodies actually will follow the light," he says, explaining it exacerbates sleep problems that are already too common in society. And it's not magnified to a degree that we would all say 'Gee, this is irreversible damage.' But why add one more thing to mess up our biology?" said Dr. Ralph Downey.
