Tonight, while most of us are sleeping, time will "spring forward."
At 2 a.m. tomorrow morning, Sunday, March 11, we'll set our clocks forward one hour - losing an hour of sleep - for daylight savings time.
Daylight savings time has changed in the past few years. Though we used to spring forward on the first Sunday in April and fall back on last Sunday in October, Congress changed the date several years ago, which added more daylight saving time to the calendar. This year, it will run from March 11 until Nov. 4.
The only states which don't do daylight savings time are: Arizona, Hawaii, Puerto Rico or the U.S. Virgin Islands.
