AIBA has rescheduled the International Boxing Day from July 22 to August 27 to connect the date with the first edition of the AIBA World Boxing Championships, which was held in Havana, Cuba in 1974. 

The competition was held between August 17 and August 30, 1974, where 11 champions were crowned and the host country topped the medal table. 

International Boxing Day originated in Russia, in 2017, following the initiative of Umar Kremlev in his role as Secretary General of the Russian Boxing Federation. In 2019, AIBA recognized and designated International Boxing Day to be celebrated every year and encouraged the global boxing family, fans, partners and stakeholders to join forces in celebrating.
