Get ready to fall back this weekend.
Daylight Saving Time ends at 2 a.m. Sunday meaning you should set your clocks back one hour before you go to bed Saturday night. The tradition of "falling back" means you will get an extra hour to sleep Sunday morning but also signals the start of dark afternoons.
The switch pushes sunrise and sunset back an hour, meaning there will be more light in the morning with darkness coming sooner in the afternoon. On Sunday, sunset time will be around 4:56 p.m. CST.
Most computers and cell phones now change their clocks automatically, but you will still need to fix your watch, microwave and car. The twice-a-year change is also a good time to check the batteries in your smoke detector.
Daylight Saving Time has been practiced on and off in the U.S. since 1918. current schedule, set through the Energy Policy Act of 2005, puts Daylight Saving Time starting the second Sunday in March and ending the first Sunday in November.
Hawaii and Arizona don't observe Daylight Saving Time, meaning there's no springing forward or falling backward on the clocks. U.S. territories such as American Samoa, Guam, Puerto Rico and the Virgin Islands don't make the change, either.
