That's why many equatorial cities and countries do not participate in Daylight Saving Time.
In locations closer to the equator, daylight hours and nighttime hours are nearly the same in length throughout the year. In order to minimize the confusion, Congress passed the Uniform Time Act in 1966, which standardized the length of Daylight Saving Time for the country.ĭaylight Saving Time is most helpful to those who live farther from the equator, where daylight hours are much longer in the summer than in the winter. This meant some cities were an hour behind others even though they were only separated by a few miles on a map. In the years after World War II, individual states and communities decided whether they wanted to continue observing Daylight Saving Time and when to do so. Daylight Saving Time was originally instituted in the United States during World War I and World War II in order to take advantage of longer daylight hours and save energy for the war production. However, it did not become a standard practice in the United States until 1966. The idea was first suggested in an essay by Benjamin Franklin in 1784, and later proposed to British Parliament by Englishman William Willett 1907. On the first Sunday in November, we “ fall back" and rewind our clocks to return to Standard Time.īut where did Daylight Saving Time come from? And how is it useful? By “ springing" clocks forward an hour in March, we move an hour of daylight from the morning to the evening. Each year, in the wee hours of a Sunday morning in March, 60 minutes vanish from the clock and the time reappears each year in November! No, it's not a magic trick - it's Daylight Saving Time!ĭaylight Saving Time (or “ Summer Time," as it's known in many parts of the world) was created to make better use of the long sunlight hours of the summer.
