"Belize September Celebrations Belize’s liveliest time of the year comes in September, when the entire country celebrates independence for three entire weeks leading up to Sept. 21. The major towns and cities host various events, and a countrywide calendar is published on Sept. 1, allowing you to follow along with the fun wherever you might find yourself in Belize . The most popular events are a steel pan concert called Pan Yaad, held in Belize City, and two full-blown carnival parades. Belize City Carnival, with soca and Caribbean music blaring, is held in mid-September, while Orange Walk Carnival takes place on Independence Day and celebrates Mestizo heritage. Take advantage of low-season fares to get a unique culture-filled experience in Belize in September."
