Software Freedom Day

Software Freedom Day is dedicated to free and open-source software. Celebrated on the third Saturday of September each year, the day highlights the value of software that people can use, study, modify, and share.

History of Software Freedom Day

The modern free software movement is closely associated with Richard Stallman, who announced the GNU Project in 1983. His goal was to support software freedom and give users the ability to understand, change, and share the programs they use.

This idea became an important part of computing culture. Free and open-source software has helped developers, students, organizations, and everyday users collaborate, learn from existing code, and build new tools.

Software Freedom Day was first observed in 2004. It is coordinated by the Digital Freedom Foundation and supported by local teams around the world through events, workshops, and educational activities.
