The idea arises in the 18th century, but did not materialize until World War
Twice a year we ask ourselves if it is time to advance or delay the clock one hour. An exported gesture from the United States. He went to Benjamin Franklin, the politician and inventor Benjamin Franklin, in 1784, proposed an hour change for energy savings. It was during his time as the United States ambassador to France. He sent a letter to the newspaper ‘The Journal’ in Paris proposing various measures to save energy and wrote a treaty to reduce the cost of light.
A proposal that had to wait for 200 years, until William Willett would recover again. However, he raised transitions of 20 minutes a week to allow the change to be more bearable.
However, it was not until World War I when the time change was applied. The Kaiser Guillermo II of Germany, on April 30, 1916, imposed a summer schedule, a measure that was taking shape in the European continent. And in World War II, the United States government forced all states to establish a summer schedule to save in energy.
Origin and reasons in Spain
In 1918 there is the first record of this practice with a royal decree to save coal. Subsequently, its use was changing for several times.
Our country adopted it on March 16, 1940. Before that each province had its own time according to its geographical situation. And during the Spanish Civil War there were two schedules according to the Republican side or the national side. But in the forties, Franco decided to establish that our country is in the European central schedule (GMT+1), which is that of Germany, to promote contact with the German country and with Hitler.
However, it would not be until 1973 that the change became definitive. The reason was the oil crisis. This change is argued that it is a government measure for citizens to adapt to the so -called summer schedules and winter schedules to take advantage of as many hours of light. The cause that promoted this practice has its motivation in the belief that it saves important energy amounts taking full advantage of the amounts of natural light.
The Institute for Diversification and Energy Savings figure in 5% the savings that are currently achieved with the hourly change. While others argue that Spain has many hours of light for its geographical situation and the change of time has no effectiveness. And this change that takes place twice a year will continue to present at least until 2026, as published by the BOE. But the debate of whether it really is an effective measure is still alive.
Other details
Russia managed to establish time change in 1917, but the initiative only lasted five months. And it tried between 1981 and 201.1 but its use was canceled. Currently, only 70 countries practice it, and Japan is the only country that has never practiced time change.
In March 2019, the European Parliament approved to end the two annual schedules, and let each of its member states decide whether to stay with the summer or winter.
