The United States Marine Corps Birthday is observed worldwide every November 10, commemorating the establishment of the Continental Marines by the Second Continental Congress in 1775. Originally celebrated on July 11, the official holiday was moved to November 10 in 1921, and the first formal ball took place in 1925. Celebrations include a traditional ball and cake-cutting ceremony, which has been performed since 1956, where the first slice of cake is passed from the oldest Marine present to the youngest. Prior to 1952, festivities varied and included dances, musical performances, sporting events, and mock battles, but they were standardized after that year. The celebration often features readings, banquets, dancing, a pageant of uniforms, and a unit run, reflecting the rich history and camaraderie of the Marine Corps.
