Daylight Saving Time officially ended at 2 a.m. last night. Did you remember to set your clocks back an hour?

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

If you're contacting friends or business in other states, remember that Arizona, Puerto Rico, Hawaii, U.S. Virgin Islands and American Samoa do not observe Daylight Saving Time.

Daylight Saving Time begins again on March 10, 2013.
