World Maritime Day is observed worldwide during the last week of September, with the specific date chosen each year. This annual observance, organized by the International Maritime Organization (IMO), was launched in 1978 and originally took place on March 17 before being moved to its current timeframe in 1980. The day aims to recognize the achievements of the international shipping industry and promote maritime safety. The main event is held at the IMO Headquarters in London, United Kingdom, and since 2005, a formal parallel event has been hosted each year by an IMO member state, which may occur on a different date. Each year, a new theme is selected, and member states are encouraged to hold events and activities focusing on this theme throughout the year.
