Extra hour myth
As a former Meteorology major I feel I have to set the record straight on the "extra hour of sunlight" myth.
Regardless of what time you have your clocks set in the winter/spring the sun shines for 12 hours. You don't get an extra hour of daylight, you get an extra hour of work. At this time of year we are receiving almost 12 hours of sunlight.
Moving the clocks ahead one hour doesn't give us 13 hours because while turning the clocks forward pushes sunrise an hour it also pushes sunset the same amount of time.
