Every year there is a subject that leaves people a little confused: which days of the new year will the time change? In 2025, the time change occurs at two different times: in early spring and autumn. These changes follow a fixed pattern, always happening on the last Sunday morning of March and October, which makes it easier to remember the dates. But what is the purpose of this change? Find out more in this article.
The transition to daylight saving time occurs in early spring. In 2025, it will be on March 30th that the clocks will be moved forward one hour, according to . This means that, from that date onwards, the days will seem longer, allowing us to better enjoy the afternoons with more natural light.
The main purpose of daylight saving time is to save energy by maximizing the use of sunlight. By moving the clocks forward, the period of light available during the working day is extended, reducing the need for artificial lighting in the afternoons and early evenings.
The change to winter time, or standard time, occurs in the fall. In 2025, it will be on October 26th. That morning, the clocks should be set back one hour, going from 02:00 to 01:00. This change allows for more natural light in the mornings, a necessity during the darker months of the year.
The adjustment to winter time is based on simple logic: as winter days are shorter, this system seeks to make the most of sunlight in the early hours of the day. However, afternoons get darker much earlier, which can change our perception of time and influence our mood and daily routine.
Despite this, there is an immediate benefit that pleases many: gaining an extra hour of sleep in the early hours of the move.
What do the experts say?
In recent years, the effectiveness of time changes has been the subject of debate. Some experts question whether this system still makes sense today, suggesting that the economic benefits may not be as significant as initially thought. Furthermore, there are concerns about the impact of these changes on people’s well-being, who may find it difficult to adapt to the new schedule. In some countries, they are already considering eliminating these seasonal changes, but for now, they continue to be a reality in many places, including Portugal.
