The idea of implementing a time change arose already in the 18th century thanks to Benjamin Franklin. It was first voted for in France only in 1916, during the First World War. Then the state sought to achieve savings in coal resources.
This measure was abandoned in 1944, but was reintroduced in 1975, 3 years after the oil crisis and soaring energy prices. In a decree issued on September 15 of the same year, this measure was called an attempt to reduce the time of artificial lighting. So it has always been a cost-effective approach and, perhaps despite itself, an environmental one.
This practice gradually spread throughout the European Union in 1980. And if initially each country set the dates for changing the time at its own discretion, then since 2001, a directive from the European Commission has led to the harmonization of the process.
