Spain's clock change debate: GMT+2, seasonal blues and bills

Clock change: the debate Spain never settles

On the last weekend of October the clocks go back one hour and Spain once again argues about the same thing it has for decades. The clock change is not just a household nuisance: it is a European decision that carries a one-hour offset from the time zone the country geographically belongs to. In A Coruña, the sun will rise on 24 December at 09:04 and set at 18:02; with daylight saving time, it would be 10:04 and 19:02. In the Balearic Islands, some 40 minutes earlier. That asymmetry — Galicia at the western edge of the time zone, the Balearics at the eastern end — explains why the same measure feels like a relief in some provinces and a curse in others.

The discomfort is not only logistical. Some describe the change as the starting gun for a season of low mood: it gets dark before you leave work, the body wants to hibernate and the lack of light takes its toll on sleep and spirits. The discussion quickly splits into two camps: those who defend winter time as the only sensible option and those who argue that the real problem is the time zone, not the seasonal change.

Why Spain lives an hour ahead of its solar clock

The most repeated argument is that Spain should be on GMT rather than GMT+1. With daylight saving time, the offset reaches GMT+2, which in practice means that in June the sun does not set until after ten at night in many areas. For a portion of participants, that artificial shift is the real problem: the issue is not moving the clock back and forth twice a year, but correcting the time zone to align with the sun.

The geographical reference is the Iberian Peninsula and its position relative to the Greenwich meridian. The most frequently cited calculation puts the winter sunrise in A Coruña at 09:04, while in the Balearic Islands it would be some 40 minutes earlier. The conclusion drawn is that the same official time produces radically different experiences depending on the longitude of the place.

Some go further and advocate GMT+0 all year round. The proposal is not new, but dissatisfaction with daylight saving time revives it every autumn. The political cost of touching the time zone is high: it means coordinating the change with Brussels and accepting that daylight hours shift for everyone.

The impact on mood: from autumn slump to seasonal disorder

The clock change coincides with the natural reduction in daylight hours in the northern hemisphere. For many people, that drop translates into a seasonal dip in mood with a clinical name: seasonal affective disorder. Symptoms include fatigue, drowsiness and lack of motivation, and they usually appear in autumn and winter.

The recommendations circulating in the conversation include exposure to natural light in the morning, keeping fixed sleep and meal schedules and getting some exercise. For northern places where the sun barely rises, the 10,000-lux light lamp is mentioned as an alternative: they cost 40-80 euros and can be used while having breakfast or reading. Checking vitamin D levels is also suggested — often low between November and March at high latitudes.

Drug treatment is not the first option. It is only considered if the slump is intense, lasts for weeks and affects work or daily life. Psychological therapy adapted to the winter pattern and light therapy are the first-line interventions.

Energy consumption: does the clock change save anything?

The classic justification for the clock change is energy saving. However, the conversation questions whether that saving actually exists. The argument is that peak electricity consumption occurs in the evening, at sunset, not in the morning, so moving the clock forward or back would have a limited or null effect on bills.

The debate on savings intersects with that of lighting and heating. Some argue that winter time means higher heating and lighting bills because people spend more time at home with the lights on. Others claim the opposite: that winter time concentrates daylight in working hours and reduces consumption during the evening peak.

The available evidence does not settle the question. What does seem clear is that the clock change has not delivered significant savings on household bills, and that its economic impact is marginal compared with other variables such as energy prices or appliance efficiency.

The political and generational divide

The clock change has stopped being a technical discussion and become a political marker. Some attribute it to a European decision that Spain obeys without questioning, while others frame it within a broader debate about sovereignty and Brussels bureaucracy. The reference to Francoism appears in the conversation as a rhetorical device to criticise the imposition of the current time.

The divide is also generational and geographical. Those who get up early out of work necessity defend winter time because it lets them leave home in daylight. Those who work in the afternoon or have flexible schedules prefer summer time to enjoy more hours of light at the end of the day. Parents of young children point out that a ten in the morning sunrise is madness for a child's routine.

The result is a country split between those who want to leave the clocks alone in winter and those who want to move them forward for good. Neither option pleases everyone, and the twice-yearly change remains the lesser evil.

What will happen with the clock change in Spain

The European Union has been discussing the abolition of the clock change for years, but the decision has been repeatedly postponed. Consensus among member states has not been reached, and Spain has not taken a definitive position. Meanwhile, the clock change continues to be applied twice a year.

The most likely hypothesis is that the change will remain in place in the short term, with periodic reviews. Social pressure exists, but there is no clear political majority to tackle the time zone. The cautious prediction: if anything changes, it will be the time zone, not the seasonal change. And that, in Galicia, would miccionan even later sunrises in winter.
