When do we go to daylight saving time?

After the arrival of spring last Sunday, March 20, the night of Saturday 26 to Sunday 27 March the time will be changed to adapt to the new summer time: at 2:00 a.m. the clocks will advance until 3:00 a.m.while in the Canary Islands at 01:00 will be 2:00. Therefore, on that day you will sleep one hour less and the days will begin to be longer.

With this time change, all member countries of the European Union without exception they comply with the European Directive 2000/84/CE. The change is mandatory and always occurs on the same dates and times throughout the EU, so there is no chance that a Member State will not apply this time change.

Why is the time changed?

The first time change was applied for the first time with the goal of saving energy and making more use of sunlight. Germany and Austria were the first countries to do so in Europe on April 30, 1916. However, there is a history in Canada, in the town of Port Arthur (now Thunder Bay) who made this change in 1908 and, a few years later, were imitated by other towns in the country.

In Spain, until the year 1918 there was not a first published rule related to the seasonal time change. It was a decree in which it was indicated that the official time was brought forward as a measure to save coal. Over the years, watches have been adapting but not in a fixed or orderly way. Sometimes, the time was changed only in some areas of the country, it was not done regularly and this practice was even abandoned for some years, such as between 1950 and 1973.

In 1974 came the oil crisis and many countries, Spain among them, adopted these time changes again. Since then, we have continued to move our clocks forward and backward without interruption.

Controversy with the change of daylight saving time

In 2018, a proposal was made to eliminate the time change and a process was initiated so that, if the member countries agreed, the change could be suppressed in 2019. However, the then Twenty-Eight considered that the initiative was premature and the decision was postponed.

Would it be healthier to keep winter time all year round?

The Commission launched the questionnaire to eliminate the clock change after the European Parliament asked it to review the clock change directive, given that several scientific studies had shown that it could have negative effects on health despite the fact that it allows energy savings.

“Both the darkness in the morning and the light at night delay the internal clock, producing a mismatch,” warns the Spanish Sleep Society (SES). According to the organization, These changes cause “insufficient, disorganized and poor quality sleep” that can promote the onset of disease such as cancer, Alzheimer’s and high blood pressurebut also “the obesity, diabetes, heart attack, stroke, depression and anxiety“.

Likewise, and according to the SES, altering the time zone causes tend to sleep less on weekdays and sleep longer on holidaysa situation that can favor poor work and school performance.

When will the last time change be in Spain?

The Official State Gazette (BOE) publishes the start and end of the summer time period corresponding to the years 2022 to 2026. This year the time change that will mark the end of summer time will take place on October 30, when at 3:00 in the morning the clock will be moved back 60 minutes.

In the BOE, in addition, they appear reflected the days of the next time changes of the next years, in which 2:00 a.m. will be 3:00 a.m.: March 27, 2022, March 26, 2023, March 31, 2024, March 30, 2025 and March 29, 2026.
