One might think after the Y2K problems a few years ago, we might not want to HARD-CODE dates and times into our software anymore. Lets hope we get better at this in the future.

In August 2005, the United States Congress passed the Energy Policy Act, which changes the start and end of DST as observed in the United States. Some additional countries/regions are following the U.S. change. As a result, DST will start three weeks earlier on March 11, 2007, and end one week later on November 4, 2007 — resulting in a new DST period that is four weeks longer than previously observed. These dates are referred to in this article as the extended DST period.

Daylight saving time rules

1987 to 2006   Daylight saving time begins (shifts time one hour forward) at 2 A.M. on the first Sunday in April and ends (shifts time one hour back) at 2 A.M. on the last Sunday in October.

Starting in 2007   Daylight saving time begins at 2 A.M. on the second Sunday in March (three weeks earlier) and ends at 2 A.M. on the first Sunday in November (one week later).

  • In 2007, daylight saving time will be observed March 11, 2007, through November 4, 2007, in areas of the United States and Canada that observe daylight saving time.
  • In 2007, the additional time period includes March 11, 2007, to April 1, 2007, and October 28, 2007, to November 4, 2007. These dates are referred to in this article as the extended DST period.
