The Free Software Foundation (FSF) turns forty on October 4, 2025 and we will end our thirties on a high note! Throughout 2025, we're celebrating the fortieth anniversary of the Free Software Foundation (FSF) with several initiatives from LibreLocal month in May to the in-person celebration in October to a free software hackathon in November. All these activities aim to bring the international free software community together, celebrate forty years of activism and all that we've achieved together, and discuss what we can do next to make the world freer. When we look back to 1985, we can see just how many stepping stones on the road to software freedom we've already laid together. We're eager to continue building the road ahead with you. Are you ready?
Below, see the timeline of events for all the exciting activities we planned for your. We look forward to celebrating with you!
