The following calendar has been created specifically for the dates related to the 2026 celebrations, both the 20th anniversary of Wikimedia CH and the 25th anniversary of the founding of our most important and successful project, Wikipedia. This is not a replica of Wikimedia CH/Calendar, which is primarily maintained by the community, but some dates may appear twice.
In this calendar, you may announce any Wikimedia-related events taking place in Switzerland that are connected to the 2026 anniversary celebrations — whether or not they are supported by Wikimedia CH — in the language of the event. You may also add international meetings and events, provided they are directly linked to the anniversaries.
