Why July 20 is International Chess Day: how the celebration began

Every July 20, chess players, clubs, schools and federations around the world celebrate International Chess Day. The date was not chosen for a famous game or world championship—it marks the birth of chess's international governing body.

FIDE was founded in Paris on July 20, 1924, during the first unofficial Chess Olympiad. The new federation gave international chess a shared institution and adopted the motto *Gens una sumus*: We are one family.

The annual celebration followed in 1966, when July 20 began to be observed internationally in honor of FIDE's founding. More than five decades later, on December 12, 2019, the United Nations General Assembly formally proclaimed July 20 as World Chess Day. The UN resolution highlighted chess as a tool for dialogue, education, inclusion and a culture of peace.

The holiday is modern, but the game is ancient. A leading historical theory traces modern chess to *chaturanga*, played in the northern Indian subcontinent during the Gupta period. The game moved west to Persia as *chatrang* and *shatranj*, then continued through the Arab world and Europe, changing along the way into the chess played today.

International Chess Day has since become both a celebration and an invitation to bring new people to the board. FIDE's centenary edition in 2024 produced a Guinness World Record, with more than 7.28 million games played in 24 hours across over 350 events worldwide.

For 2026, FIDE invited communities to take chess beyond traditional playing halls: into schools, public squares, historic locations and unusual settings. Celebrations were reported from Sri Lanka, the Maldives, Pakistan, India, the United Kingdom, South Africa, Ireland and Spain.

The competitive side of the day remains part of the tradition too. In St Petersburg, a 20-round International Chess Day blitz produced a 19/20 winning score.

A century after FIDE's creation and 60 years after the first International Chess Day observance, July 20 still carries the same simple idea: chess belongs everywhere, and to everyone.
