what date and when will it end?


Daylight saving time is approaching. It will then be necessary to advance the hands of one hour (that is to say one hour less of sleep during this night). The time change was originally motivated by energy savings, but a vote by MEPs in 2019 marked its end for 2021. Except that the Covid has been there and the European Council has still not ratified it .

The daylight saving time change is approaching. Get ready to put your clocks forward one hour on the weekend of March 25-26: we switch to summer time on Sunday 26 at 2 a.m. Here’s everything you need to know about the time change.

The next time change that will take us to DST will be on Sunday, March 26, 2023. More precisely on the night of Saturday 25 to Sunday 26 March. At 2 a.m. in the early morning, it will be 3 a.m.

Since 1996, the time change dates have been the same throughout the European Union. We therefore switch simultaneously to summer time on the same day at the same time in the 27 Member States. They have agreed to change the time twice each year, with a transition to summer time fixed since the last Sunday of March. The changeover time, 2 a.m. on a Sunday, was chosen to minimize any risk of transport and telecommunications disruptions.

Why do we change the clock?

In France, the first transition to summer time took place on June 14, 1916, and lasted until 1945 at the end of the Second World War, when we returned to constant time. The idea, at the outset, is to reduce energy waste at a time when lighting is one of the most important energy consumption items. Moving back or forward one hour thus makes it possible to vary lighting needs, in particular in offices and businesses which have legal opening and closing times.

The return of the time change took place in 1976 in the wake of the oil crisis of 1973. At the time, public and private lighting was still mainly based on very energy-consuming incandescent lamps. But despite the recovery, and the transition to more energy efficient devices (LED lighting, disappearance of filament lamps and energy consumption indices for a wide variety of devices), the time change has persisted. And it was even harmonized in the European Union in the early 2000s.

However, according to a study by ADEME, the more widespread the use of products and devices with high energy efficiency, the less the benefits of the device are real. The agency notes that savings are still made on lighting, they are limited. A joint study with EDF, ADEME and the Ministry of Industry concluded that it was possible to save 0.015% of total energy consumption in 2014 thanks to summer time. In other words: not much.

Is the time change bad for your health?

This is a recurring criticism of the time change: it would be bad for your health. Several recent studies show that advancing the clock in the spring can temporarily reduce sleep time. This would increase the number and severity of heart attacks for at least seven days after the time change. Beyond that, there would be more work and traffic accidents.

In France, the return to winter time leads to a peak in accidents for about a week, especially at the end of the day when the excess of accidents reaches up to +47% for pedestrians. Beyond that, it poses problems in telecommunications and international transport. So for a long time it has been questioned.

A report submitted to the Senate in 1997 estimated that “the advantages announced or expected from the half-yearly change of time are not significant enough to compensate for the disadvantages felt by the populations”. The question of its abolition has been on the table regularly for several years.

When is the end of the time change?

Between September 2018 and March 2019, a large public consultation asked Europeans to vote for or against the change of time. This consultation resulted in a true plebiscite in favor of the abolition of the change of time twice a year. The French consultation, for example, received 2,103,999 responses with “83.71% of respondents [qui se sont prononcés ] to put an end to the change of time twice a year”.

Similar consultations elsewhere yielded overwhelmingly similar results. The question was therefore examined by MEPs who decided on Tuesday 26 March 2019 to remove the seasonal time change from 2021. However, the text states that “Member States will retain the right to decide their time zone”. A majority of French people supported maintaining summer time.

The decision still needs to be validated by the European Council and then transposed by the Member States. Still, the health crisis has completely turned the calendar upside down. The end of the time change is put on hold and the question is no longer on the agenda. At least, for now.
