About Olympic Day

Olympic Day is observed internationally on June 23 as the annual celebration of the Olympic Movement. The International Olympic Committee coordinates the observance with National Olympic Committees around the world.

IOC historical material traces the first World Olympic Day to June 23, 1948, after the 42nd IOC Session approved the project in St Moritz in January 1948.

Why Olympic Day matters

The date commemorates June 23, 1894, when the Paris congress supported Pierre de Coubertin’s proposal to revive the Olympic Games and the modern Olympic Movement was founded.

Modern Olympic Day programming centers on participation, movement and Olympic values. It is an IOC-led international observance, not a statutory public holiday in every country.

History of Olympic Day

The IOC says the project for a World Olympic Day was approved at the 42nd IOC Session in St Moritz in January 1948.

The first World Olympic Day was held on June 23, 1948, with ceremonies organized by nine National Olympic Committees: Austria, Belgium, Canada, Great Britain, Greece, Portugal, Switzerland, Uruguay and Venezuela.

The 1978 Olympic Charter recommended for the first time that National Olympic Committees regularly organize an Olympic Day, strengthening the recurring global framework.
