About International Chess Day
International Chess Day is celebrated on July 20th, the date the International Chess Federation (FIDE) was founded in Paris in 1924. Chess originated in 6th-century India as chaturanga and is now played by an estimated 600+ million people. The day, recognized by the UN in 2019, is marked with tournaments, simultaneous exhibitions and online events that have boomed since 'The Queen's Gambit.'

Chess began in 6th-century India as chaturanga, a four-division army game, traveled to Persia as shatranj — where 'checkmate' was born from shah mat, 'the king is helpless' — and reached Europe through the Islamic world. The modern rules arrived around 1475 in Spain, when the queen was transformed from the weakest piece into the most powerful, an era some historians link to powerful European queens like Isabella of Castile.
The Numbers Behind the 64 Squares
An estimated 600 million people play chess regularly. The number of possible chess games — the Shannon number — is around 10¹²⁰, more than the number of atoms in the observable universe. The longest tournament game on record lasted 269 moves and over 20 hours (Nikolić vs. Arsović, 1989) and ended in a draw.
In 1997, IBM's Deep Blue defeated world champion Garry Kasparov, the first computer victory over a reigning champion — a milestone in the history of artificial intelligence.
Why July 20?
International Chess Day marks the founding of FIDE, the International Chess Federation, in Paris on July 20, 1924. The UN officially recognized the day in 2019. The game is enjoying a historic boom: after 'The Queen's Gambit' aired in 2020, chess set sales jumped by hundreds of percent and online platforms gained tens of millions of new players.
