International Lego Day is celebrated worldwide every January 28, marking the anniversary of the patenting of the modern Lego brick design in 1958. The day honors the legacy of the Lego Group, which began in 1932 when Danish carpenter Ole Kirk Kristiansen founded a company producing wooden toys. The name "Lego" is derived from the Danish phrase "leg godt," meaning "play well." After transitioning to plastic toys in 1947, the company introduced the Automatic Building Bricks, which evolved into the iconic Lego bricks we know today. The holiday, initially informal, is now supported by the Lego Group, recognizing its marketing potential. In addition to toys, the Lego Group operates Legoland theme parks in various countries, including Denmark, Germany, and the United States, and has developed a film franchise based on its construction toys.
