Because of Daylight Saving Time. That information is from an insurance institute as they see this every year when DST goes into effect. There is no corresponding effect in the fall when we go off DST. I also heard on the news yesterday that a study shows it does not really save energy. Probably because it gives those who want to get melanoma faster more time to run around in their vehicles. For astrologers is it as pain in the ass because it makes timezones for areas inconsistent.
