Daylight Time. By act of Congress, civil clocks in most areas of the United States are adjusted ahead one hour in the summer months (known as daylight time) and returned back one hour in the winter months (known as standard time).
The dates marking the beginning and end of daylight time have changed as Congress has passed new statutes. As of 2007, daylight time begins in the United States on the second Sunday in March and ends on the first Sunday in November. On the second Sunday in March, clocks are set ahead one hour at 2:00 a.m. local standard time (which becomes 3:00 a.m. local daylight time). On the first Sunday in November, clocks are set back one hour at 2:00 a.m. local daylight time (which becomes 1:00 a.m. local standard time).
These dates were established by Congress in the Energy Policy Act of 2005, Pub. Almanacs. Wordnik: clouds. Calendrica. Lunaria. Water in situ. Wind forecast.
