The Wikipedia 25th Birthday Celebration commemorates twenty-five years of Wikipedia's journey as one of the world's largest and most widely used collaborative knowledge platforms. From its founding in January 2001, Wikipedia has grown into an extraordinary repository of human knowledge — built entirely by volunteers, freely available to anyone, and continuously improved by a global community dedicated to the principle that knowledge belongs to everyone.
This celebration recognises the remarkable contributions of the volunteer community whose collective efforts have made free, reliable knowledge accessible to millions of people around the world. It brings together Wikimedia contributors, newcomers, educators, students, and free knowledge enthusiasts to celebrate Wikipedia's legacy while inspiring future participation in Wikimedia projects.
Organised by Wiki Club SATI, the event is designed to be inclusive and welcoming — whether you are an experienced Wikimedian or someone discovering Wikipedia's volunteer community for the very first time.
