Before 1892: Brussels Ran on Its Own Sun
Solar noon in Brussels arrived roughly 16 minutes later than in Greenwich. The city sits at 4°17' east of the Greenwich meridian. Every town set its public clocks to its own sun.
This local standard was called Brussels Mean Time. The offset was approximately UTC+0:16. Train schedules, post offices and public clocks all used it. Other Belgian cities kept their own local times. Brussels Mean Time became the de facto national reference because the capital's observatory and railway network adopted it.
1892: Belgium Switches to Western European Time
Belgium moved to Western European Time (WET), UTC+0, identical to Greenwich Mean Time. France had done the same in 1891. Belgium followed its largest neighbour to simplify railway timetables, telegraph communications and cross-border trade.
The Netherlands, Luxembourg and France all used WET. For the first time, Belgium had a standardised zone matching the rest of Western Europe. The arrangement held for 22 years.
1914: Germany Imposes CET
German forces occupied Belgium in August 1914. One of the earliest administrative changes was to the clocks. Occupation authorities ordered Belgian railways and public institutions onto Central European Time (CET), UTC+1, the time used in Berlin.
The logic was straightforward: align occupied Belgium with German military and railway schedules. Civilian life followed. By 1916 the entire occupied territory ran on Berlin time.
After the November 1918 armistice, Belgium returned to WET. The exact switch date is poorly documented, but the country was back on Western European Time by 1919.
1940: Germany Imposes CET Again. This Time It Sticks
Germany invaded Belgium in May 1940. On 20 May 1940, occupation authorities ordered the country onto CET once more.
When the war ended in 1945, Belgium did not revert to WET. The reasons were economic. Trade patterns, railway connections and business relationships were by then deeply integrated with neighbours using CET: the Netherlands, Luxembourg, Germany, France and Switzerland. Shifting back would have moved the working day by an hour relative to those partners. France also stayed on CET after the war. The same reasoning applied. Reverting was too disruptive.
Belgium has remained on Central European Time ever since.
Why the 1945 Decision Held
Two forces locked the choice in place. Belgium's main trading partners all used CET. A different zone would have complicated freight logistics, railway schedules and financial market hours. And the EU institutions based in Brussels operate on CET. Shifting the host country's clocks would create friction for the thousands of diplomats and civil servants crossing borders daily.
1977: Belgium Adopts EU-Wide Daylight Saving
Belgium ran daylight saving during both world wars. Germany introduced it in 1916 as a fuel-saving measure. In the post-war decades, Belgium used it inconsistently.
That changed in 1977. After the 1973 oil crisis, energy concerns drove EU-wide DST harmonisation. Belgium adopted the common rule: clocks go forward one hour on the last Sunday of March and back on the last Sunday of October. All EU member states switch at the same moment, 01:00 UTC. In Brussels, that means 02:00 CET or 03:00 CEST.
This system still applies.
Clock Change Dates for 2026 and 2027
On 29 March 2026 at 02:00, clocks go forward to 03:00. CET becomes CEST.
On 25 October 2026 at 03:00, clocks go back to 02:00. CEST becomes CET.
The same pattern repeats in 2027: forward on 28 March, back on 31 October.
Why the EU Proposal to End Clock Changes Stalled
In 2018, the European Commission proposed abolishing seasonal clock changes across the EU. The European Parliament voted in favour in 2019. Each member state would choose between permanent summer time (CEST, UTC+2 year-round) or permanent winter time (CET, UTC+1 year-round).
Belgium never declared a formal preference. The proposal stalled in the Council of the EU. Member states could not agree on a common position. As of 2026, no implementation date exists.
What Permanent Change Would Mean
On the December solstice in Brussels, the sun rises at 08:42 and sets at 16:38. That is 7 hours and 56 minutes of daylight. Evenings would stay lighter. On the June solstice, Brussels sunrise is 05:28 and sunset is 21:59, with 16 hours and 31 minutes of daylight. Neither option has secured consensus among member states.
What Time Is Brussels on Right Now?
Brussels uses Central European Time in winter (CET, UTC+1) and Central European Summer Time in summer (CEST, UTC+2). It shares the same clock as Paris, Berlin, Rome, Madrid and Amsterdam. London is one hour behind.
On 15 January 2026, relative to Brussels on CET, New York is 6 hours behind. Los Angeles is 9 hours behind. Dubai is 3 hours ahead. Mumbai is 4.5 hours ahead. Singapore is 7 hours ahead. Tokyo is 8 hours ahead. Sydney is 10 hours ahead. Johannesburg is 1 hour ahead. São Paulo is 4 hours behind. Chicago is 7 hours behind. Paris shares the same time.

The IANA Identifier
The machine-readable time zone name for all of Belgium is Europe/Brussels. There are no regional differences. Flemish, French and German-speaking communities all share the same clock.
