Spring Forward

          Daylight Saving Time, also known as "Summer Time", begins on the second Sunday in March and ends on the first Sunday in November (but not in Arizona and Hawaii).

          The clock goes forward one hour at 2:00 AM on the second Sunday in March and back to normal time at 2:00 AM on the first Sunday in November.
          These dates were recently modified with the passage of the Energy Policy Act of 2005. Prior to 2007, daylight time in the United States began on the first Sunday in April and ended on the last Sunday in October.
