(KSL News) -- Don't forget to fall back this weekend.
Daylight Saving Time ends early Sunday morning so you need to set your clock back an hour before you go to bed Saturday night.
Benjamin Franklin first came up with the idea of Daylight Saving in 1784. Germany and Austria were the first countries to enact Daylight saving in 1916 as a way to conserve fuel during World War I.
It was first observed in the US in 1918, but was later repealed because it was unpopular with the public. Then in 1966 Congress made it official. Only Arizona and Hawaii don't observe Daylight Saving.
Daylight-saving time returns April 2. Beginning in 2007, daylight saving time will begin the second Sunday in March and end the first Sunday of November.
