If you need a little extra sleep you can sneak in an hour this weekend.

Daylight Saving Time (DST) ends this weekend.

Remember to set your clocks back an hour at 2:00am on Sunday, November 3, 2013.

The clocks move forward again on March 9, 2014, which is when you'll have to give back that extra hour.

Many people use the "spring forward, fall back" reminder to keep track of which way the clocks are supposed to be turned, but that is only in the places that observe the oft-controversial practice.  Parts of Arizona, American Samoa, Hawaii, Puerto Rico, and the U.S. Virgin Islands have chosen not to observe Daylight Saving Time.

In 1996 the European Union adopted "European Summer Time," which runs from the last Sunday in March through the last Sunday in October.

During World War I and World War II DST was adopted in an effort to save fuel.  Afterward some states continued the observance; others did not.  To lessen the confusion Congress adopted the Uniform Time Act in 1966, which standardized things - at least for those states that wished to continue the practice.
