Culture Freedom Day is observed worldwide every third Saturday of May. This international observance was initiated by the Digital Freedom Foundation in 2012 and is rooted in the free culture movement that began in 2004, with Lawrence Lessig recognized as its founding figure due to his influential book "Free Culture: How Big Media Uses Technology and the Law to Lock Down Culture and Control Creativity." The day celebrates the principles of free access to artistic works, encouraging artists to make their creations available for redistribution and study, opposing the practice of copyright extensions. Typical customs include various exhibitions such as photo displays, concerts, and movie screenings, showcasing that culture is free and accessible to everyone.
