In 2026, Belgium continues the practice of seasonal clock changes, known as Daylight Saving Time (DST). Twice a year, residents of the country adjust their clocks: in the spring they move them one hour forward, and in the autumn — one hour backward. This system makes it possible to use more daylight in the evening hours, save energy, and adapt to natural human biorhythms. Although the European Parliament passed a resolution in 2019 regarding the possible abolition of clock changes, the final reform has not yet been introduced, so the habit of resetting clocks remains.
Dates of clock changes in 2026
| Shift | Date | Change Time | What happens |
| Spring (Daylight Saving Time) | Sunday, March 29, 2026 | 02:00 → 03:00 | An hour is lost, evenings become lighter |
| Autumn (Winter Time) | Sunday, October 25, 2026 | 03:00 → 02:00 | An hour is returned, mornings are lighter, evenings are darker |
Traditionally, the time change in the EU occurs on the last Sunday of March and the last Sunday of October. All of Belgium uses a single time zone: CET in winter (UTC+1) and CEST in summer (UTC+2).
Why clocks are changed
The DST system was first introduced more than a hundred years ago to save electricity. The main idea is to use daylight as efficiently as possible: in the spring, clocks are moved forward so that the evening is lighter; in the autumn, standard time is returned so that the morning is lighter and more convenient for work and study.
Modern research shows that shifting the clocks can affect health: sleep is disrupted, and stress increases, especially among people with chronic illnesses. On the other hand, more daylight after work encourages outdoor activities, walks, and sports.
How to prepare for the clock change
For most people, the time change passes almost unnoticed because smartphones, computers, and smart devices do it automatically. Nevertheless, old mechanical watches, household appliances, and wall clocks require manual adjustment.
Before the spring shift, it is useful to gradually shift bedtime 10–15 minutes earlier over several days. This helps the body adapt to the reduced hour of sleep. Morning exposure to light also helps align biorhythms. During the transition to winter time, the extra hour of sleep allows the body to recover; however, the evenings become darker, which can affect mood and productivity, so it is worth planning activities with the earlier sunset in mind.
Time changes in an international context
In most countries of the European Union, the transition dates coincide with the Belgian ones. Exceptions occur in certain countries: Iceland, Russia, and Turkey do not change their clocks at all. In the UK, a proprietary system operates — the transition to British Summer Time (BST) differs from CET/CEST. When planning travel or business calls, it is important to take these differences into account so as not to miss meetings and to synchronize time.
Comparing the Belgian experience with other countries, it is clear that synchronization within the EU makes life and business communication more convenient, but individual habits and health still remain important when adapting to clock changes.
Practical tips for English-speaking residents of Belgium
Shifting to summer and winter time remains a part of daily life in Belgium. To minimize the negative impact, it is recommended to prepare in advance: check clocks on household appliances, adjust sleep schedules, and plan daily activities around the light.
Knowing the exact dates of the clock changes — March 29 (summer time) and October 25 (winter time) 2026 — helps to effectively organize work, leisure, and trips. Thus, even despite possible legislative changes, the habit of resetting clocks remains relevant for now and requires simple but useful preparatory actions.
