Set Your Clocks Back—Daylight Savings Ends on Sunday
These dark mornings might have you wondering: When does Daylight Savings Time end?
Those 7:30 a.m. commutes will get darker before they get lighter. Daylight Savings Time will soon end–officially at 2 a.m. on Sunday, Nov. 4.
Remember, you’ll “fall back” and set your clocks back one hour, though many electronic devices automatically adjust when Daylight Savings 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.
So, why do we go through this ritual year after year? Daylight Saving Time, first established in 1918, is designed to add an hour of sunlight to the end of the day during the warm weather months, according to the National Institute of Standards and Technology. The period of time was extended in 2007 by one month to encourage energy savings, and now runs from 2 a.m. the second Sunday of March (March 13) to 2 a.m. on the first Sunday of November.
Arizona, Puerto Rico, Hawaii, U.S. Virgin Islands and American Samoa do not observe Daylight Savings Time.
Daylight Savings Time will begin again on March 10, 2013.
