DAYLIGHT SAVINGS TIME
The current March-November system the US follows began in 2007, but the concept of “saving daylight” is much older. It’s debated who originally came up with the idea, but Benjamin Franklin appeared to have first mentioned it in 1784, when he wrote a letter to the editor of the Journal of Paris.
DST wasn’t widely used until more than a century later, though. Several countries, including Britain and Germany, implemented DST during World War I. The practice aimed to cut artificial lighting use so troops could conserve fuel for the war. But the US didn’t standardize the system until 1966, when it passed the Uniform Time Act.
