7 December
In 1996, the United Nations General Assembly proclaimed 7 December as International Civil Aviation Day, and urged governments, as well as national, regional, international and intergovernmental organisations, to take steps to observe it (resolution 51/33 of 6 December).
In 1992 the Assembly of the International Civil Aviation Organisation (ICAO), a United Nations specialised agency, declared the day to highlight and advance the benefits of international civil aviation. Observation of the Day started on 7 December 1994 - the fiftieth anniversary of the signing of the Convention on International Civil Aviation, which established the International Civil Aviation Organization (ICAO).
