International Civil Aviation Day: 07 December

The International Civil Aviation Day is celebrated every year on December 7 to recognize the importance of aviation to the social and economic development of the world.
The Day was established in 1994 to celebrate the 50th anniversary of the establishment of International Civil Aviation Organization (ICAO) [Headquarter-Montreal, Canada].
The United Nations General Assembly proclaimed the day in 1996.
The ICAO Council has selected the special collective 5 year theme for 2019-2023: “Advancing Innovation for Global Aviation Development”.
