International LEGO Day is celebrated on January 28 to honor the day in 1958 when the official patent for the modern LEGO brick was filed, a system so precise that bricks made in 1958 still fit bricks made today.

The company’s journey began in 1932, when Ole Kirk Christiansen founded the LEGO Group in Denmark. Originally a producer of wooden toys, the company transitioned to plastic bricks in the late 1940s. By 1958, the design had evolved into a stable, universal system.
