The morning of next Sunday, March 29, begins "summer time"

Thus, the European directive 2000/84 / EC which is still in force, without exception, in all member states of the European Union.

The time change is currently subject to study of the respective countries that make up the Union after the European Commission carried out in 2018 a public consultation in which more than 80% of the 4.6 million citizens who participated were in favor to end the time changes.

The Committee of Transport and Tourism Ministers of the European Parliament approved in March last year to postpone this decision until at least 2021.

The time change provokes a wide debate among various social groups. In recent years, various reports have been produced that have taken into account not only aspects related to possible energy savings, but other issues related to the need to harmonize schedules, road safety, working conditions and their repercussions on the health, among others. These reports coincide in pointing out that the benefits of the time change do not seem decisive.

In August 2018, and at the request of the Council of Ministers, an Expert Committee was created in our country, which includes leading professionals from all sectors involved. Its objective is to analyze the factors for and against the time change, as well as the impact that the decision to permanently adopt one of the two time alternatives would have.

The results of this analysis will be taken into account by the Government to make the decision about the time zone in Spain.

On the other hand, the Sociological Research Center (CIS) carried out in November of last year a survey in which 65% of the participants declared in favor of staying in the summer time.


After the publication of the proposal for a Directive, the European Parliament's Industry, Research and Energy Committee produced a report prepared by Sven Schulze in which it is pointed out that, although seasonal changes in time may produce savings, they are marginal and not there is certainty that they occur in all Member States. Compared to those who obtain savings, the countries may be affected by an increase in energy consumption.

The report also indicates that there may be savings in lighting, but that it is not so obvious that the same happens with heating, as it could even increase its consumption. Furthermore, according to the experts, the results are difficult to interpret since they are highly influenced by external factors such as meteorology, geography and user behavior.

In Spain there are no updated reports to ensure that the time change has associated energy savings. Furthermore, the new demands for energy efficiency in lighting, in air conditioning systems and in the buildings themselves, as well as the progressive introduction of self-consumption, significantly alter the analyzes that were originally used to calculate these data.

From the Institute for Diversification and Energy Saving (IDAE), in any case, citizens are encouraged to practice -as far as possible- measures that promote efficiency and energy savings in their domestic consumption, especially while the containment measures established in the Royal Decree-Law 8/2020, of March 17, of extraordinary urgent measures to face the economic and social impact of COVID-19. To this end, in the Web page of the Institute a guide with practical advice is available, and the online training platform.

Time zone

Spain, geographically, is located in the UTC / GMT + 1 zone, coinciding with most of Europe with the exception of the United Kingdom, Ireland and Portugal, which remain at UTC / GMT + 0. This ascription of a spindle is the one that has marked the Spanish "official time" since 1940, advanced by 60 minutes to "universal time".

In the latitude of our country the hours of light are the same, around 10 in winter and about 14 in summer, but it is not sunrise or sunset at the same time in the east as in the west, and there may be more than an hour of difference. from one end to the other. Vigo, for example, is the European city in which it is late at night.
