This Daylight Savings Time advisory.
February 7, 2007
On August 8, 2005, the U.S. Congress passed and President George W. Bush signed into law the Energy Policy Act of 2005. Among other changes, this act modifies the start and end dates for daylight saving time (DST) in the following geographic regions:
– United States except Arizona, Hawaii, Puerto Rico, the U.S. Virgin Islands, and American Samoa.
– The Navajo Nation in Arizona does observe DST
– All of Canada
When this law goes into effect on March 11, 2007, DST will start three weeks earlier and will end one week later than what has traditionally occurred. This change is typically referred to as DST 2007. Under the DST 2007 rules, in the United States, clocks change at 02:00 local time.
Following are the key dates for 2007:
On March 11, 2007, clocks will move forward from 01:59 to 03:00.
On November 4, 2007, clocks will move backward from 01:59 to 01:00.
