Belgium operates on Central European Time (CET) during winter months, which is 1 hour ahead of Coordinated Universal Time (UTC+1). During daylight saving time, observed from the last Sunday in March to the last Sunday in October, Belgium switches to Central European Summer Time (CEST), which is UTC+2.
All of Belgium follows the same timezone. Major cities including Brussels, Antwerp, Ghent, Bruges, and Liège all observe the same time. Brussels serves as the de facto capital of the European Union, making Belgian time important for EU business.
Brussels is home to the headquarters of NATO and the European Union, making it one of the most important cities for international diplomacy. When scheduling meetings with EU officials, Central European Time is often referred to as "Brussels time" in political circles.
