The pandemic has prevented the EU plan to review the time change, although choosing what time to stay is a complex issue.

A good watch in the process of change from two to three.

At Two o’clock in the morning, peninsular time, next Sunday, March 28, the clocks will again advance sixty minutes and Spain will thus return to the official summer time, with the eternal controversy about the real benefits of this adjustment that occurs twice a year.

In Spain summer time was first adopted in 1918 for economic and political reasons, according to an article published by Doctor in Physics Pere Planesas in the Yearbook of the Madrid Astronomical Observatory, as a result of the coal shortage caused by the First World War and to harmonize the schedule with that of neighboring countries.

In the first half of the 20th century, the official time “was applied discontinuously and with little consistency in the dates”, first as a result of the civil war of 1936-39 and, later, of the Second World War, but after the oil crisis of the 70s, summer time was reinstated in many European countries -Spain did it from 1974- and since 1980 it depends on European directives, says Planesas.

In recent years, various experts in the field have defended the need to set a time and keep it all year round since differentiating between winter and summer time “could make sense until forty or fifty years ago but not so much now” when, as explained by Ricardo Irurzun, from Ecologistas en Acción, as a result of the last time change, “there is no way to verify whether or not energy is saved” since there are no estimates “in a well-studied way” in recent years in this regard.

What is proven is that the variation in hours of light that the human body receives affects its body and “although we adapt quickly to a change of this type”, when it is forced for reasons unrelated to biology “there is a dysregulation of hormonal levels” which implies, among other things, a decrease in melatonin or “sleep hormone”, which affects both the rest and the performance of the person.

This has been confirmed by the expert in neurovascular research of the Higher Council for Scientific Research (CSIC), Ricardo Martínez, who also recalled that for people with psychotic disorders, such as those suffering from manic-depressive psychosis, “spring feels awful to them, since his state of mind worsens among other reasons for having more hours to think ”.

In this situation, the European Commission announced in 2019 its intention to put an end to the changes definitively, so that each European country chose what time it preferred for the whole year, and the European Parliament chose 2021 as the time when the new regulations would go into effect.

But, as with many other provisions, the health crisis and the confinements since March 2020 altered the calendar by generating a significant delay in the debate and the regulation process And, to this day, it does not seem that this year is going to be the one to say goodbye to the time change: in fact, we already know that on October 31 we will recover the “60 lost minutes” by resuming winter time.

Sunrise at 10 in the morning

The Greenwich meridian would cross Spain at the height of Alicante and, therefore, the time of the United Kingdom, Ireland, Portugal and the Canary Islands would correspond to us: GMT + 0. And so it was until 1940, when the government of Franco it was set to “German time.” That is, it adopted the schedule of Berlin Y Paris, which is equivalent to GMT + 1 and is also called Central European Time (CET). In winter, this allows for sunrise before eight in the morning in October and for nightfall before eight in the afternoon.

Maintaining summer time in the autumn and winter months would be especially noticeable in the westernmost provinces, particularly in Galicia, another community that has already raised the time exceptionality to catch up with Portugal. As calculated by the Chronobiology Laboratory of the University of Murcia, this will imply that the Sun does not rise until nine in the morning and even ten o’clock on the shortest days of the year

Much more advantageous, according to experts, would be keep winter time all year round: “With this modification, the Sun would rise one hour earlier from the end of March to the end of October, facilitating a more natural awakening, the schedules would approach the solar time that corresponds to Spain and the feeding and sleeping schedules would be brought forward “ summarized José María Fernández-Crehuet, professor of Economics and Innovation at the Polytechnic University of Madrid.
