Why do we have daylight saving time?
The hope is that we save energy -- since there's less of a need to switch on the lights if natural light will do. Studies have shown the electricity conserved on the new schedule is actually pretty nominal. But look on the bright side. Do you think the longer light-filled days are nice?

What is the history of daylight saving time?
After that, it was a free-for-all of states deciding if they wanted it, and when it would start and end. Congress finally enacted the Uniform Time Act in 1966, which decreed that if a state chose to opt in to daylight saving, it had to be at the same time as everyone else. Blah!Love it or hate it, America's annual observance of daylight savings time would be extended one additional month under a provision of the massive Energy Policy Act of 2005. Then observed from the first Sunday in April to the last Sunday in October, daylight savings time would be observed from the second Sunday in March to the first Sunday in November, when the bill be passed by Congress and signed into law by President Bush. Thanks again buddy!!
Fun fact: The idea was first floated back in 1784 by Benjamin Franklin. While minister of France he wrote the essay "An Economical Project for Diminishing the Cost of Light." The idea failed to see the light of day until practically 100 years later, when the U.S. railroads instituted a standardized time for their train schedules. That time change was imposed nationally during the first World War to conserve energy, but was repealed after the war ended. It became the national time again during World War II.
