It’s time to get back that hour of sleep lost last spring with the return of Standard Time.

Every Autumn, we say good-bye to Daylight Saving Time and hello to Standard Time when most Americans turn their clocks back one hour.

Standard Time returns at 2:00 a.m. on Sunday, Nov. 1st.

Daylight Saving Time gives people that extra hour of sunlight during the warm summer months, then comes Standard Time, when that extra hour of daylight is snatched away in the evening and shifted to the morning hours. It’s an age old tradition that officially isn’t that old.

The practice of Daylight Savings Time became official in 1975 as a way to save energy.

Standard Time used to begin in the middle of October but it was moved to the first weekend in November in 2007.

Daylight Saving Time will return the second Sunday in March.

Research shows more car accidents happen in the first weeks after the return to Standard Time as people try to adjust their sleep patterns. Students have trouble staying awake during morning classes and the change is especially difficult for shift workers and others that work nights or long hours.
