Daylight Saving Time

[Dave Monroe]

Starting in 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. L. no. 109-58, 119 Stat 594 (2005)....
