Time to turn the clocks back.
Most of the United States will end daylight saving time Sunday, Nov. 2, at 2 a.m. by reverting to standard time.
Daylight savings is meant to save energy by providing more daylight during the evening.
Studies by the Department of Energy show that daylight saving time trims the country's electricity use by about 1 percent each day because less electricity is used. Though daylight saving time was adopted in 1918, observing it began in earnest in 1966. Most countries around the world also use it. Japan, India and China, however, do not. In the European Union, Greenwich Mean Time ended Sunday, Oct. 26.
Fire and police departments encourage people to use this time to change the batteries in their smoke detectors when they change their clocks.
