This weekend we are going to summer time!

During the night from Saturday to Sunday, you will have to move the hand forward one hour in order to switch to summer time, but why?

Although our smartphones, computers and tablets perform this time change automatically, our watches and clocks will have to do it manually. This time change on the night of Saturday March 26, 2022 to Sunday March 27, 2022 is, unfortunately, not the last. But, do you know why? And do you know the origin of these time changes as winter and summer approach?

1916: introduction of the first time change in France

France is not the first country in Europe to have introduced a time change. The first countries to introduce it were the United Kingdom and Ireland during the First World War. On our side, the French government of the time only took action in 1916 with the ambition of reducing the country’s energy needs thanks to more sunshine.

This amendment was subsequently abolished in 1945 for a return of the time change in 1975 following a rise in the price of oil. It was not until 1998 that Europe introduced this change of time on a large scale.

Has the expected objective been achieved?

A study interesting study carried out in 2010 by Ademe, the French Environment and Energy Management Agency, shows that these time changes in 2009, the reference year of the study, made it possible to save 440 GWh this which represents the annual consumption of 800,000 households. This result is accompanied at the same time by a reduction of 44,000 tonnes of CO2 emissions, still in 2009. According to calculations made by Ademe, this time change, if still active in 2030, could reduce CO2 emissions by 110,000 tonnes.

But is it perceived in the same way by the population? No, some people have been campaigning for years to stop the time change in France, as in Europe. The impact of this schedule change is not as beneficial for human beings with more or less significant disturbances and an increase in road accidents.

This struck a chord with the Council of the European Union, which had planned the end of the time change for 2019 after a favorable vote by the European Parliament. European countries were therefore responsible for choosing a definitive time, winter time or summer time. However, this would cause logistical problems between a country running on summer time and its neighbor on winter time. It would seem logical that all European countries have a single time.

The European Affairs Committee of the National Assembly has interrogates several French people in order to know their opinion concerning these changes of hours. This survey shows that 83.71% of the French population against 16.29% wants the end of the time change. A second question asked during the survey shows more divergence. Indeed, 59.17% of people want to keep summer time against 36.97% who want to keep winter time.

Nevertheless, the COVID-19 pandemic has been there, putting a stop to many projects and in particular this change of time. Therefore, on the night of March 26 to 27, we will (again?) switch to daylight saving time.

Last time change? No, we will advance one hour in the night from Saturday to Sunday

Before all the countries of the European Union agree, ink will have flowed on papers, or water under the bridges. Therefore, it will still be necessary advance its clock one hour on the night of March 26 to 27, 2022. That is to say that Sunday, at 2 am, it will actually be 3 am, that is “one hour less under the duvet”!

We look forward to seeing you on the night of Saturday October 29 to Sunday October 30, 2022 to, this time, set our clock back one hour to enter winter time.

Moreover, here are the next dates for the time changes:

  • from Saturday October 29 to Sunday October 30, 2022 (winter time)
  • from Saturday March 25 to Sunday March 26, 2023 (summer time)
  • from Saturday October 28 to Sunday October 29, 2023 (winter time)
  • from Saturday March 30 to Sunday March 31, 2024 (summer time)
