LEGO Build Day is observed worldwide every December 27, celebrating creativity and the joy of building with LEGO bricks. Participants are encouraged to gather their spare LEGO pieces, construct unique creations, and share their results using the hashtag #LEGOBuildDay. This tradition, initiated by LEGO, promotes imaginative play and collaboration, allowing individuals to build anything from simple structures to complex designs. The event draws inspiration from LEGO's history, which began in 1932 when Danish carpenter Ole Kirk Christiansen founded the company, initially producing wooden toys. The modern design of LEGO bricks was patented in 1958, leading to the brand's rise as the largest toy manufacturer by sales today. For those seeking ideas, the official LEGO website offers challenges and prompts to inspire creativity.
