According to the National Institute of Standards and Technology, Daylight Saving Time will end on November 4, 2007 at 2:00 a.m. local time for most of the United States and Canada.
This change is different from previous years due to a U.S. mandated daylight saving time change, which was caused by the Energy Policy Act of 2005.
The next change to regular Daylight Saving Time will be in 2038.
