French Community Day, observed in Belgium every September 27, celebrates the French Community of Belgium, which consists of Francophone Belgians primarily residing in the Walloon Region and the Brussels-Capital Region. This community, making up about 41% of the country's population, has its own parliament, government, administration, and flag, known as the bold rooster. The holiday commemorates a significant event during the Belgian Revolution when the royal army failed to reclaim Brussels from Walloon revolutionaries. First celebrated in 1975, French Community Day features various activities such as concerts, theatrical performances, and sporting events, although schools are closed while many businesses remain open.
