North Korea's Party Foundation Day is a holiday as odd as the country's Foundation Day. Both are very loosely based on actual events and both commemorate a false date: the North Korean state was not established on September 9, 1948, nor was the Party founded on October 10, 1945.

The northern Korean section of the Communist Party of Korea was established on October 13 and the Workers' Party of North Korea on July 29, 1946. The actual WPK was born on June 30, 1949.
