On the last Sunday of October, like every year, winter time comes into effect.
Specifically, at 04:00 on Sunday morning, October 26, 2025, clocks should be moved back one hour, that is, to 03:00.
The time change is implemented in all European Union countries, as part of the common energy saving policy, although its abolition has been considered for years - but without a final decision being made until now.
Why is this change happening?
As early as 1784, Benjamin Franklin had expressed the opinion that changing the clock would bring energy savings. Wars, and specifically, during World War I, the great needs for energy, brought about the first implementation of changing the position of the hands, with Germany being the first country to move the time forward 60 minutes in 1916. The same tactic was followed by England and the United States.
After the end of World War I, this tactic was no longer considered necessary and was banned. However, World War II brought it back into people's lives and it has been in effect ever since.
Time change: effects on sleep and adaptation
The time change on October 26th will give us an extra hour of sleep, as the night will last 25 hours instead of 24.
However, experts emphasize that the human body needs time to adapt even to this seemingly favorable change.
Our biological clock is more sensitive than mechanical clocks, and adaptation can take several days. This highlights the importance of gradually preparing for the time change.
Not all countries change the clock
The time change occurs in more than 70 countries around the world. Many European countries change their time at the end of March and October (solar time).
The only countries that do not are Iceland, Turkey, Belarus, Russia, Armenia, Azerbaijan and Georgia.
Most Asian countries such as India, Japan, China and Mongolia choose not to use daylight saving time, while many Middle Eastern countries avoid changing the clock.
In Iran and Jordan, this is a recent change, while Egypt decided to bring it back in 2023.
In Africa, many countries do not use it, except for Morocco and the Canary Islands that are nearby, but the latter belong to Spain.
