Daylight saving time change March 2026: when it happens, why it’s done, and how it can help you save energy

March is back, and with it, daylight saving time. It's time to move the clocks forward again to make the most of natural light and adapt our daily habits. Every year, this small adjustment raises different questions: When does the time change? Why do we move the clocks forward? And does it really save energy?

In this article, we'll tell you everything you need to know about the time change and give you some useful tips to make your home more efficient.

 When does daylight saving time start in March 2026?

The first thing you need to know to get organised is the specific date of the change. 

Exact date: last Sunday in March (28 March)

Daylight saving time in March 2026 is scheduled to begin on Sunday 28 March. This date marks the start of daylight saving time in 2026. This allows us to keep our clocks synchronised with daylight hours.

 At 2:00 it will be 3:00 → it moves forward 1 hour

At 2:00, we will go directly to 3:00. This means that we will lose an hour of sleep that night. Sunrise will be later, but in exchange we will enjoy more natural light in the afternoon. 

Daylight saving time begins

With the time change this March, 2026 daylight saving time officially begins and will remain in effect until the last Sunday in October. The biannual adjustment seeks to reduce the need for artificial light; the later it gets dark, the later we will turn on the lights.

Why do we change the clocks in spring?

Moving the clocks forward is not a whim, but is intended to make more efficient use of energy.

Taking advantage of more hours of natural light

The most obvious reason is to take advantage of natural light. By setting the clock forward, the days naturally become longer, which reduces the need for electric lighting in homes and offices.

Synchronising social schedules with daylight hours

The change also seeks to align our activities with daylight hours, so that working and leisure hours coincide mainly with daylight.This can improve well-being and productivity, especially in northern regions.

Impact on energy savings (myth vs reality)

Although the time change is said to save energy, recent studies are not 100% conclusive. In some regions, savings in lighting are real, but increased use of air conditioning or heating may partially offset this. Even so, taking advantage of more natural light remains a tangible benefit.

How the time change affects your energy consumption

This March, the time change will clearly influence our energy consumption habits. Understanding these effects allows us to adjust our routines and reduce our electricity bills.

More natural light in the afternoon

When the clocks go forward, the afternoons become longer. This means we will need electric light for less time, especially in common areas such as the living room or kitchen.

Air conditioning adjustments by region

The effect on heating and air conditioning depends on the region. In cold areas, for example, setting the clocks forward can increase morning heating consumption. Conversely, in warmer regions, the need for air conditioning in the afternoon is reduced.

Changes in domestic habits

The time change can also be a good time to review domestic habits: turning off lights when not in use and resetting timers and automatic lighting schedules can be useful for saving energy while taking advantage of daylight hours.

Tips for taking advantage of the time change and saving electricity in 2026

With these steps, moving the clocks forward in 2026 will not only be a matter of adjusting your watch, but also an opportunity to improve energy efficiency in your home:

• Take advantage of daylight: make the most of the natural light that enters your home.
• Reschedule appliances: check if off-peak hours have changed with daylight saving time for washing and ironing, thus reducing electricity consumption.
• Efficient lighting: replace your conventional light bulbs with energy-efficient LEDs.
•  Set timers for heating and air conditioning: adjust schedules so that they only run when you need them.

 Daily routine: do as much as you can during daylight hours (e.g., reading in natural light) to minimise the use of artificial light.

Will this be one of the last time changes? The situation in the EU

The end of daylight saving time may be closer than we think, but there is still no clear consensus on the situation.

In 2018, a proposal to abolish daylight saving time was presented by the European Commission. The key elements of that proposal, as stated in the official information, were to abolish biannual time changes (twice a year) in all European Union countries and to establish a notification system for Member States wishing to change their official time.

Its abolition has been debated since 2019

Within the framework of the Council of the European Union, the proposal has been followed up at various meetings. On 6 June 2019, seasonal time change was on the agenda of the EU Transport Council. Subsequently, on 2 December 2019, at the Transport Council, the Finnish Presidency provided information on the status of the proposal. It also developed a tool to assess the amount of daylight in different scenarios. However, the Council has not yet reached a common position on this issue.

Proposals to maintain summer or winter time

The European Parliament approved its position in March 2019, voting in favour of abolishing summer and winter time. However, for the proposal to become law, the Council of the European Union must adopt a position, and both institutions must reach an agreement, on which there is still no clear consensus.

Current status for 2023

No final decision has been made, nor has a deadline been set for doing so. In the meantime, the current system remains in force. Current regulations provide that all member states must switch to summer time on the last Sunday in March and return to winter time on the last Sunday in October.

Differences between countries and government positions

EU legislation allows member states to decide which time zone they wish to be in. The EU currently recognises three official time zones:

• Western European Time: Ireland and Portugal.
• Central European Time: seventeen member states, including Spain.
• Eastern European Time: eight member states in Eastern Europe, such as Greece.

Knowing the effects and timing of March 2026 clock change will help us not only to adapt better, but also to take advantage of the light and improve the energy efficiency of our homes. Setting the clock forward may seem like a small gesture, but with smart habits, it becomes a tool for saving more and living in tune with natural light.

"Fixed schedules were created at the same time as the railway."

The first time change took place during wartime: on April 30, 1916, clocks were adjusted throughout the German Empire, the Austro-Hungarian Empire, Bulgaria, and Turkey. Later, the rest of the European countries and the United States adopted the idea.

During World War II, the United States enforced daylight saving time in order to save as much energy as possible in war zones. It was also implemented during the 1973 oil crisis.

Spain did not have a unified time until the 20th century, when the Greenwich meridian became the standard. Previously, official time was based on the Madrid meridian, and the country had several time zones. On April 15, 1918, a summer time schedule was officially established, although in some years (from 1920 to 1923 and in 1925) it was decided not to change the clocks.

With the Civil War came timekeeping chaos: the Republic had one time, while the Francoist territories had another. After the war, there were years when the time was not changed: 1941, 1947, and the entire period between 1950 and 1973. Since 1973, clocks have been changed every year in March and October.

"The farther north you live, the more energy is saved with daylight saving time."

History of Daylight Saving Time

• Ancient civilizations:

  They divided the day into 12-hour periods.

   

• 14th century: construction of mechanical clocks

  They adjusted the days to 24 hours

   

• 1784: Benjamin Franklin proposes the first idea of daylight saving time.

  By waking up earlier, people could make better use of sunlight and save on lighting. The population largely ignored the idea.

   

• Late 19th century:

  The modern time system was established, largely due to the expansion of the railway.

   

• 1908: William Willet propone el primer documento para ahorrar energía.

  Based on Franklin’s ideas, he suggested advancing clocks by 80 minutes during summer.

   

• 1916: Implementation of daylight saving time

  It was first applied during World War I to save coal.

   

• 1973: Daylight saving time reintroduced

  During the 1973 oil crisis, when Arab oil producers stopped exports, the United States and Europe were forced to reduce energy consumption.
