Are you ready to gain an extra hour? Daylight Saving Time ends, officially, at 2 a.m. on Sunday, Nov. 4. 

Remember, you’ll "fall back" and set your clocks back one hour.

When you change your clocks in the fall and spring, it’s also a good time to change smoke detector batteries and to make sure the devices are in working order.

Arizona, Puerto Rico, Hawaii, U.S. Virgin Islands and American Samoa do not observe Daylight Savings Time.

Then on March 10, 2013, it will be time to "spring forward."
