In 2021, the last Sunday in March falls on March 28, when clock indicators will go an hour ahead.
That night, that is, at 3:00am, the clock indicators will move an hour ahead, to 4:00.
The next time change will take place in October (2021) and possibly March 2022.
The plenary of the European Parliament had decided to abolish the time change in 2021, but this issue has stagnated, as the coronavirus pandemic has monopolized events, not only in Europe, but around the world.
According to the European Parliament's decision, the time change must stop on the last Sunday of March 2021 for the countries of the European Union, which want to maintain daylight saving time permanently, while for Member States wishing to have winter time, the change will take place on the last Sunday in October 2021.
Why the time is changing
The measure of time change has the main advantage of saving energy. In total, during the seven months of daylight saving 210 hours of electricity by taking advantage of the Sun.
In the 1970s, under the influence of the oil crisis, most European countries tried to exploit daylight in the best possible way.
Since 1996 there has been a single, pan-European regulation, during which in Spring we turn the clocks one hour ahead (so that we can use daylight for an additional hour), while in Autumn we bring them back an hour.
