How Daylight savings Work - Navo

• According to astronomers, the big bang created both time and space about 14 billion years ago. Ever since, seconds and minutes have spooled outward, like an infinitely large ball of twine unraveling as it rolls on a ceaseless journey. 
• Humans have long tried to affect this unraveling process, to make it happen more slowly or quickly. Einsten even predicted it was possible, if we could travel at the speed of light.
• Humans have devised ways to manipulate it to their advantage. Daylight saving time (DST), the period of year when clocks are moved one hour ahead to create more sunlit hours in the evening, stands as one of the best examples of how this can be done.
• Benjamin Franklin first conceived of DST in 1784, while serving as U.S. ambassador to France. According to the story, he woke one day at 6 a.m. and noticed how many of his fellow Parisians were still in bed, with shutters drawn to keep out the light. 
• As a result, people were sleeping during sunlit hours and burning candles longer into the evening. 
• The United States follows rules established by the Energy Policy Act of 2005. According to that legislation, daylight saving time begins in the U.S. (a country in the Northern Hemisphere) at 2 a.m. on the second Sunday in March. That's when many Americans move clocks forward by one hour and, if they're diligent citizens, replace their smoke-detector batteries. It ends about eight months later; at 2 a.m. on the first Sunday in November, clocks move back an hour, and standard time reigns again.
