When and why is the clock changed?

In many countries, including Spain, we still change the clocks twice a year. The original idea behind this practice was make better use of daylight hours and reduce energy consumptionadapting the clocks to the evolution of light throughout the seasons.

The first change takes place in the early hours of the last Sunday of MarchIn mainland Spain, at 02:00 AM the clocks go directly forward to 03:00 AM. In the Canary Islands, where they are always one hour behind, the jump occurs from 01:00 AM to 02:00 AM. This is what we often hear as "at two o'clock it will be three," with the Canary Islands' unique characteristic of "one hour less."

The second change takes place at the end of October, also in the early hours of Sunday morning. In this case, the clock will Turn back one hour to enter winter timeIn the Peninsula, 03:00 will become 02:00, while in the Canary Islands, 02:00 will become 01:00 again.

Although we are used to this dance of hours, in recent years there has been much debate about the real usefulness of the change. Some studies question whether significant energy savings can be achieved. They also point to the potential negative effects on biological rhythms. The European Union even considered eliminating daylight saving time and gave member states a timeframe to decide, but so far there is no final agreement.

There has been much discussion about whether it would be better to keep summer or winter time permanently. Many experts believe that Winter time is better suited to the body's natural light needsWhile a large part of the population prefers summer time because of the longer daylight hours in the afternoon, which is associated with more outdoor leisure and a feeling of safety on the street.

Today we still change the clocks twice a year, and until a reform is approved at the European level, It's advisable to check the time settings on mobile phones and devices before each change. to avoid surprises with alarms, appointments or trips.

That's why it's so important to take a few minutes to check these settings on your mobile phone, smartwatch, and computer, especially If you're going to rely on an alarm for a trip, a work shift, or an exam the morning after the time change.

There are also very old or more basic devices that do not support automatic synchronization with time servers and depend entirely on manual adjustment. In these cases, it will be necessary Remember to manually adjust the clock each time the seasons change..
