Daylight Saving Time

New DST Rules

Starting in March 2007, daylight time in the United States will begin on the second Sunday in March and end on the first Sunday in November. These dates were recently modified with the passage of the Energy Policy Act of 2005, Pub. L. no. 109-58, 119 Stat 594 (2005).

Not all places in the U.S. observe daylight time. In particular, Hawaii and most of Arizona do not use it. Indiana just recently adopted the use of it beginning in 2006.

Many other countries observe some form of "summer time", but they do not necessarily change their clocks on the same dates as the U.S.
