Those 7:30 a.m. commutes will get darker before they get lighter. Officially, Daylight Saving Time doesn’t end for a couple more weeks — officially at 2 a.m. on Sunday, Nov. 4. 

Remember, you’ll “fall back” and set your clocks back one hour. Many electronic devices automatically adjust when Daylight Saving Time begins or ends.

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 device are in working order.

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

It begins again on March 10, 2013.
