Daylight Saving Time 2012 ends in the U.S. today (November 4, 2012) at 2 a.m. local time on your clock. Remember to fall back and set your clocks back by one hour.
In the United States, only Hawaii and Arizona do not practice Daylight Saving Time.
Daylight Saving Time used to begin on the first Sunday in April and end on the last Sunday in October. With the passage of the Energy Policy Act of 2005, it was extended by four weeks. The start date was moved to the second Sunday in March and the end date to the first Sunday in November.
One tip from the United States Fire Administration. Use Daylight Saving Time as a twice-yearly reminder to change the batteries in your smoke detectors and carbon monoxide alarms.
Daylight Savings Time 2012 will begin again on March 10, 2013.
