Daylight Saving Time Changes for 2007

The U.S. Energy Policy Act of 2005, extended Daylight Saving Time (DST) in the U.S. by approximately four weeks. As a result, beginning in 2007, DST will start three weeks earlier on March 11, 2007, and end one week later on November 4, 2007. Some hardware devices and software programs will need to be updated to show the correct time during these new DST periods.
