Daylight Saving Time

clock.jpegDaylight Saving Time has arrived again starting this Sunday, March 14, at 2 am when clocks move forward one hour. In a previous post, we discussed the laws that first enacted Daylight Saving.

Why is Daylight Saving Time so early in the year? The Energy Policy Act of 2005 changed Daylight Saving dates in 15 U.S.C. ยง260a(a) to the second Sunday in March and the first Sunday in November starting in 2007. Previously, Daylight Saving Times were scheduled the first Sunday in April and the last Sunday in October. This law also gave Congress the authority to reverse its decision to change Daylight Saving dates.

The U.S. Department of Energy studied the effects of these changes and published a report. Among its findings:

  • Changes in gasoline consumption were small.
  • Electricity usage decreased .03% in 2007.
  • Electricity savings were slightly larger during the March Daylight Saving date than the November date. Northern sections of the United States experienced more electricity savings than southern sections.
