In the period from 1933 to 1940 it was held on August 18, a free day in the calendar of that time. Later it was most usually held on the third Sunday of August, if only weather permitted.

In 1937, the parade was attended by nearly a million people, observing the masses of aircraft spelling in the sky "LENIN", "STALIN" and "SSSR".
