Civil Aviation Day is observed in Russia every February 9, celebrating the achievements and contributions of civil aviation in the country. The date marks the anniversary of the establishment of Russian civil aviation, which began on February 9, 1932, when the Council of Labor and Defense adopted a resolution to organize the Council of Civil Aviation. This led to the creation of the civil aviation fleet and the first route from Moscow to Nizhniy Novgorod. The day was officially recognized as a professional holiday in 2013, although it had been informally celebrated since 1979. Notable symbols of this day include the special flag of Russian civil aviation and the uniforms and insignia introduced in 1932. Aeroflot, the largest airline in Russia and one of the oldest in the world, is a key organization associated with this celebration.
