The event is organized in spring (30 days), summer (31 days) and late fall (30 days). It originates from the Christman market, which was organized in front of the Hamburg Cathedral on the occasion of Catholic holidays as early as 1329. Since the city came under Protestant influence, celebrations were also organized on other occasions. Hamburg Dom celebrations attract approximately 10 million tourists annually.
