What Is the Europe/Brussels IANA Identifier?
Europe/Brussels is the IANA time zone identifier for all of Belgium. No sub-national zones exist: Antwerp, Ghent, Charleroi, Liège, and Bruges all use the same identifier. One zone, one set of rules for the entire country.
The identifier lives in the IANA Time Zone Database, the canonical source for time zone data used by operating systems, programming languages, and databases. Set a server or application to Europe/Brussels and you get the correct offset and DST transitions for any date, past or future.

How Developers Should Use Europe/Brussels
Always use Europe/Brussels as the time zone identifier. Hardcoding offsets like +01:00 or +02:00 breaks when DST changes. The IANA zone handles the transitions automatically.
Common pitfalls to avoid:
- Never use
CETorCESTas a time zone identifier in code. They are abbreviations, not IANA zone names. UseEurope/Brussels. - Always store times in UTC in your database, and convert to
Europe/Brusselsonly for display. This avoids ambiguity during the "fall back" transition when 02:00 occurs twice. - Brussels is always 1 hour ahead of London, even in summer (CEST vs BST). See the Brussels vs London time comparison.
- No special handling needed for other Belgian cities.
Europe/Brusselscovers the entire country.

Europe/Brussels Covers Every Belgian City
The same identifier applies to every location in Belgium. Antwerp, Ghent, Charleroi, Liège, Bruges: all share identical current time, DST transitions, and UTC offset. Unlike the United States or Australia, Belgium has no internal time zone boundaries.
What's Next for Europe/Brussels?
The next change is Sunday 25 October 2026 at 03:00 local time. Clocks go back 60 minutes to 02:00, switching from CEST (UTC+2) to CET (UTC+1). An extra hour of sleep that night, then earlier sunsets and shorter days heading into winter. On the December solstice (21 December 2026), sunrise comes at 08:42 and sunset at 16:38: just 7 hours and 56 minutes of daylight. Plan outdoor activities accordingly.
