International Civil Aviation Day was established in 1994 as part of ICAO’s 50th anniversary activities. In 1996, pursuant to an ICAO initiative and with the assistance of the Canadian Government, the United Nations General Assembly officially recognized 7 December as International Civil Aviation Day in the UN system.

 
The purpose of International Civil Aviation Day is to help generate and reinforce worldwide awareness of the importance of international civil aviation to the social and economic development of States, and of the unique role of ICAO in helping States to cooperate and realize a truly global rapid transit network at the service of all mankind.

As the UN and world nations have now adopted Agenda 2030, and embarked on a new era in global sustainable development, the importance of aviation as an engine of global connectivity has never been more relevant to the Chicago Convention’s objectives to look to international flight as a fundamental enabler of global peace and prosperity.

International Civil Aviation Day Theme
 
Every five years, coinciding with ICAO anniversaries (2014/2019/2024/2029/etc.), the ICAO Council establishes a special anniversary theme for International Civil Aviation Day. Between these anniversary years, Council representatives select a single theme for the full four-year intervening period. 

In recognition of ICAO’s 75th anniversary, the Council selected the following theme “75 Years of Connecting the World” for the 2019 celebrations.

From now through the end of 2023, the Council has decided that the theme will be:
 

“Advancing Innovation for Global Aviation Development”
