Which historical event introduced Daylight Saving Time?

Answer 1

Daylight Saving Time has been used in the U.S. and in many European countries since World War I. At that time, in an effort to conserve fuel needed to produce electric power, Germany and Austria took time by the forelock, and began saving daylight at 11:00 p.m. on April 30, 1916, by advancing the hands of the clock one hour until the following October. Other countries immediately adopted this 1916 action: Belgium, Denmark, France, Italy, Luxembourg, Netherlands, Norway, Portugal, Sweden, Turkey, and Tasmania. Nova Scotia and Manitoba adopted it as well, with Britain following suit three weeks later, on May 21, 1916. In 1917, Australia and Newfoundland began saving daylight.

The plan was not formally adopted in the U.S. until 1918. 'An Act to preserve daylight and provide standard time for the United States' was enacted on March 19, 1918. [See law]It both established standard time zones and set summer DST to begin on March 31, 1918. Daylight Saving Time was observed for seven months in 1918 and 1919. After the War ended, the law proved so unpopular (mostly because people rose earlier and went to bed earlier than people do today) that it was repealed in 1919 with a Congressional override of President Wilson's veto. Daylight Saving Time became a local option, and was continued in a few states, such as Massachusetts and Rhode Island, and in some cities, such as New York, Philadelphia, and Chicago.

During World War II, President Franklin Roosevelt instituted year-round Daylight Saving Time, called "War Time," from February 9, 1942 to September 30, 1945. [See law] From 1945 to 1966, there was no federal law regarding Daylight Saving Time, so states and localities were free to choose whether or not to observe Daylight Saving Time and could choose when it began and ended. This understandably caused confusion, especially for the broadcasting industry, as well as for railways, airlines, and bus companies. Because of the different local customs and laws, radio and TV stations and the transportation companies had to publish new schedules every time a state or town began or ended Daylight Saving Time.

On January 4, 1974, President Nixon signed into law the Emergency Daylight Saving Time Energy Conservation Act of 1973. Then, beginning on January 6, 1974, implementing the Daylight Saving Time Energy Act, clocks were set ahead. On October 5, 1974, Congress amended the Act, and Standard Time returned on October 27, 1974. Daylight Saving Time resumed on February 23, 1975 and ended on October 26, 1975.

Answer 2

World War 1 was the historical event that introduced day light savings time. It was introduced to conserve fuel needed to produce electric power.
