Every year on February 21, communities around the world celebrate International Mother Language Day, a day to remember that every language carries stories, knowledge and identity. This year, we invite you to celebrate it together through a collaborative International Mother Language Day 2026 Datathon, on Wikidata running from February 21 to March 3, 2026.[1]

Inspired by the theme "Youth voices on multilingual education,"  this datathon is not just about editing data. It’s all about giving our languages a stronger digital presence and creating space for diverse voices in the open knowledge movement. Whether you speak a widely used language or a smaller community language, your contributions can help make Wikidata more inclusive and multilingual.

✨ What can you do during the datathon?

• Have a Wikidata Tour in your native language if you haven't 😉
• Improve labels and descriptions in your language
• Help document multilingual education initiatives
• Collaborate with other communities and learn together

We warmly welcome everyone, especially communities, user groups, wiki clubs and youth contributors to join and help shape this datathon as a collective effort.

If you're interested in participating, please visit the event page and register for the datathon.[2] If your community or user group would like to collaborate, we would love to have you with us. Let’s come together to celebrate our languages, learn from one another, and strengthen multilingual knowledge on Wikidata.💛
