Daylight Savings Time Ends: Time to Fall Back

It’s time to “fall back” again this weekend and to set your clocks back one hour when you go to bed tonight.
Daylight saving time ends for most of the country, as standard time officially begins at 2 a.m. Sunday morning.
The seven-month period of daylight saving time is mandated by governments, which began implementing the time switch during World Wars I and II to save energy and resources for the war effort.
From World War II until recently, daylight saving in the U.S. ran from April until mid-October.
In 2007, Congress adjusted daylight saving time to begin three weeks earlier and end one week later — a move they hoped would help save energy.
