CET vs CEST: how DST shifts the UTC offset
Belgium observes daylight saving time. The clock hours stay fixed (09:00-17:30), but the UTC equivalent moves twice a year.
Winter (CET, UTC+1): from the last Sunday in October to the last Sunday in March. 09:00 CET = 08:00 UTC.
Summer (CEST, UTC+2): from the last Sunday in March to the last Sunday in October. 09:00 CEST = 07:00 UTC.
2026 clock changes:
- Spring forward: Sunday 29 March 2026 at 02:00 local. Clocks jump to 03:00. Trading starts at 09:00 CEST.
- Fall back: Sunday 25 October 2026 at 03:00 local. Clocks fall to 02:00. Trading starts at 09:00 CET.

How Brussels hours line up with other European markets
Brussels shares its 09:00-17:30 window with Paris and Amsterdam. London opens at 08:00 GMT (09:00 CET in winter, 08:00 BST in summer), a 1-hour offset year-round. Frankfurt opens at 09:00 CET/CEST, same as Brussels.
Cross-market trades between Brussels and London: add 1 hour to London times to get Brussels times, in any season.
Traders in New York (6 hours behind Brussels on both 15 January and 15 July) should place Brussels orders before 11:30 New York time. That 17:30 Brussels close doesn't move. Traders in Tokyo face a harder edge. Brussels closes at 17:30, which is 00:30 Tokyo time in winter (8 hours ahead) and 01:30 in summer (7 hours ahead). Same-day orders must be in before late night Tokyo time.
