Answer 1

In the United States, Daylight Saving Time begins at 2:00 a.m. on the second Sunday of March (we set our clocks 1 hour forward) and ends at 2:00 a.m. on the first Sunday of November (when we set our clocks back 1 hour.)

For 2007, these dates are March 11 and November 4.
For 2008, the dates are March 9 and November 2.

Note that prior to 2007, DST began on the first Sunday in April and ended on the last Sunday in October.

Answer 2

The U.S started this around the time of WWII 1 hour ahead on March 11 and 1 hour back on Nov 4 to make up for the lost hour to save energy. (2am is the time the time changes)

Answer 3
