Why has daylight savings time been moved a month earlier?

Answer 1

Congress changed Daylight Savings. An amendment was added to the Energy Policy Act of 2005 (H.R. 6) by Representatives Ed Markey and Fred Upton to extend Daylight Savings Time by 4 weeks (3 weeks earlier in March and going 1 week later). This Amendment was added as an effort to save energy in the US by adding more daylight hours to the work day hoping that businesses and individuals will need less heat/lighting/etc. during that time. The Amendment was also added to decrease the number of car accidents due to poor visibility and "night blindness." Though this year the change will likely be a pain in the butt and cause problems with electronic devices, the hope is that in the long run it will save energy. H.R. 6 was signed into law in August 2005 and most of its provisions were implemented at the beginning of 2007.

Answer 2

I believe it's in an effort to save energy by aligning daylight more closely to the time most people are up and about. But this is just a guess. :-)

Answer 3

It's a way to try to conserve energy under the assumption that less electricity will be used if the sun is shining in hours that we normally use artificial light.
