This Sunday, October 28, we are facing the controversial for the second time this year Time change. On this occasion, at 3 o'clock in the morning it will be 2 o'clock, adding an extra hour of sleep in an attempt to have more light early in the morning and get a small energy saving. At least, that's what the theory says. However, at the moment of truth many are the detractors of this attack on our body, which twice a year has to adapt to a new schedule.
Why do we change the time?
The fault lies with the Community directive 2000/84 / EC, for which the last weekend of October we delayed an hour the clock to pass to the Winter time, and the last weekend of March we advance one hour to go to summer.
The idea is to adapt our schedules to natural light and thus achieve energy savings, although there are many who doubt that such savings will occur. Yes, we have more light in the morning, but in return we have less light when we leave work. In fact, the studies consulted by the European Commission indicate that the energy saving is marginal, between 0.5 and 2.5%. To this we must add, in addition, its impact on human biorhythms (in the form of fatigue or lack of concentration) during the days after Time change.
Can it be one of the last time changes?
The truth is that yes. Brussels announced this summer that it was going to propose the suppression of the change of time in the EU as a whole. The announcement was made after an overwhelming majority of Europeans said in an online survey that they were in favor of abolishing the time change: 84% of voters were in favor of having a fixed schedule.
Just two weeks later, the European Commission announced that it wants the last mandatory time change to be at the end of March 2019. And the member states that want to return to the winter time could make a last change of time on Sunday October 27, 2019. From there, the schedule would remain unchanged for all.
Is Spain in the time zone that corresponds to it?
Another recurring debate every time we change the time has to do with the Time zone in which Spain is located. That's the right one? Why do we eat between one and two hours later than the rest of Europeans?
It all started when, in the middle of World War II, Spain and the rest of European countries (except Portugal and Switzerland) advanced the time. In principle it was going to be a temporary decision, but Spain never returned to the time zone that corresponds to it: the Greenwich Meridian (GMT in winter). They also did not delay the extra time France, Belgium or the Netherlands.
For this reason, we have the Central European Time (the one in Berlin) instead of the Western Time (the one in London), so we live one hour ahead of the sun in winter and two in summer.
