My mom brought this to my attention today. Usually, Daylight Saving Time (DST) begins on the first weekend in April, and ends on the last weekend in October. President Bush signed into law the Energy Policy Act of 2005, which changes the dates when DST begins and ends to make the range of DST longer.
Instead of DST starting on April 8th this year, DST will start on March 11th. And instead of DST ending on October 28th, it will end on November 4th. This adds a couple of weeks to the DST range.
