Daylight Saving Time in the United States
The entire concept of Daylight Saving Time is based on the fact that longer afternoons are more productive - and thus more helpful for the society, as compared to longer mornings. In order to facilitate this, the clocks are reversed by an hour in such a manner that the afternoon becomes an hour longer than the morning. The brainchild of George Vernon Hudson - an entomologist and astronomer from New Zealand - DST is widely followed in the Northern hemisphere today. (Some sources suggest that the first citation of this concept was put forth by Benjamin Franklin in 1784.) The concept is relatively more popular in North America and Europe, as compared to the other continents of the world, though the practice differs significantly in both the continents.
