Daylight Saving Time

Turn the clocks ahead this Sunday.

Daylight Saving Time gives us the opportunity to enjoy extra dayliight by moving our clocks an hour forward in the spring. It was the idea of Benjamin Franklin.

Most of the United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November. In the U.S., each time zone switches at a different time.

In the U.S., clocks change at 2:00 a.m. local time. In spring, clocks spring forward from 1:59 a.m. to 3:00 a.m.; in fall, clocks fall back from 1:59 a.m. to 1:00 a.m.

In 2007, daylight time changed in the United States to the second Sunday in March, ending 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.

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

• In 2006, daylight time begins on April 2 and ends on October 29.
• In 2007, daylight time begins on March 11 and ends on November 4. [New law goes into effect.]
• In 2008, daylight time begins on March 9 and ends on November 2.
• In 2009, daylight time begins on March 8 and ends on November 1.

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.
