Don't Forget to Turn Back Your Clocks Saturday Night

By Rebecca McCarthy

Daylight Saving Time in 2013 ends in the United States on Sunday, Nov. 3, at 2 a.m.

You will be setting your clock back one hour, following the adage of “spring forward, fall back.” The “extra” hour gives you a chance to catch up on the sleep you lost in March when the clocks moved forward and Daylight Saving Time began.

• What will you do with that "extra" hour of your life? Tell us in the comments section below.

The federal government doesn’t require states to adopt Daylight Saving Time. Connecticut, like most of the rest of the United States, observes it. (Indiana used to ignore Daylight Saving Time but has gotten on board.) 

Did you know all of Arizona rejects the practice (except for the Navajo Nation, which does observe), Hawaii, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands and the Virgin Islands.

In an effort to save resources during World War II, the U.S. made Daylight Saving Time mandatory for the whole country. And it was observed the entire year.

Some studies have shown that extending Daylight Saving Time results in a reduction in energy consumption; other studies suggest just the opposite.
