Singapore runs on UTC+8 all year. No spring forward, no fall back. Brussels shifts twice: Central European Summer Time (CEST, UTC+2) from late March to late October, then Central European Time (CET, UTC+1) the rest of the year.
That makes the gap 6 hours in summer and 7 hours in winter. When it is 09:00 in Brussels in July, it is 15:00 in Singapore. When it is 09:00 in Brussels in January, it is 16:00 in Singapore. The difference feels predictable once you know which side of the DST switch you are on.
The mistake most people make: assuming the gap stays constant year-round. It does not. Mark your calendar for the last Sunday of March and the last Sunday of October. Those are the days the offset changes.
When does the Brussels to Singapore time gap change in 2026?
Sunday 29 March 2026. Brussels clocks go forward at 02:00 local time. The gap shrinks from 7 hours to 6 hours.
Sunday 25 October 2026. Brussels clocks go back at 03:00 local time. The gap widens from 6 hours to 7 hours.
If you have a standing meeting, it shifts by one hour that week. Your calendar tool should handle it if it knows both time zones.
Best time to call Brussels from Singapore
Book calls from Singapore between 14:00 and 16:00. That reaches Brussels between 07:00 and 09:00 in summer, or 08:00 and 10:00 in winter. It catches the start of the European workday.
Best time to call Singapore from Brussels
Book calls from Brussels between 09:00 and 11:00. That lands in Singapore between 15:00 and 17:00 in summer, or 16:00 and 18:00 in winter. Both windows fall inside standard Asian business hours.
Skip evening calls entirely. A 19:00 call from Brussels reaches Singapore at 01:00 or 02:00.
Can I trade Euronext Brussels and SGX in the same window?
Barely. Euronext Brussels runs 09:00 to 17:30. Singapore markets close at 17:00 Singapore time. That is 11:00 Brussels time in summer and 10:00 in winter.
You get a one to two-hour overlap. Use it for time-sensitive trades, but do not expect a full-session window. The next change on Sunday 25 October 2026 will tighten it further.
