From May 9 to June 30, 2025, the first edition of the “Month of Science on Wikipedia” challenge will take place on Czech Wikipedia in collaboration with Charles University. The goal is to expand Wikipedia’s content with scientific topics, figures, and concepts that are currently missing or in need of updates. Everyone who participates will also have a chance to win a subscription to a popular science magazine. The main edit-a-thon will take place on June 19 at 3:00 PM at Didaktikon Hybernská, Charles University.
