You will get an extra hour of sleep Sunday, Nov. 3, when everyone is required to "fall back" as Daylight Saving Time ends at 2 a.m.
Daylight Saving Time started during WWI when people were required to save energy for wartime production. It was again observed during WWII. States were eventually given the option to observe the time change, or not.
According to abcnews.go.com, a study in 2008 revealed the energy saved during Daylight Saving equaled .5 percent per day, or 1.3 billion kilowatt hours: enough to power nearly 122,000 homes for a year.
