Open Knowledge

Save the date! March 2-8, 2024

Open Data Day (ODD) is an annual celebration of open data all over the world. Groups from likely every country create local events on the day where they will use open data in their communities. ODD is led by the Open Knowledge Foundation (OKFN) and this year’s edition is co-organised by Jokkolabs Banjul (Gambia), Open Knowledge Germany, Open Knowledge Ghana, and Open Knowledge Nepal, all members of the Open Knowledge Network.

As a way to increase the representation of different cultures, since 2023 we offer the opportunity for organisations to host an Open Data Day event on the best date between March 2nd and 8th.

All outputs are open for everyone to use and re-use.

Thematic Focus: Open Data for Advancing Sustainable Development Goals (SDGs).

Following CKAN's recognition as a digital public good, in 2024 we will explore how open data is a key player in helping to achieve the UN’s Sustainable Development Goals (SDGs).

Open Data Day is for everyone!

If you have an idea for using open data, want to find an interesting project to contribute towards, learn about how to visualise or analyse data or simply want to see what's happening, then come participate!

Participation is a core value of Open Data Day, everyone is free to voice their opinions in a constructive manner. No matter your skill-set or interests, we are encouraging organisers to foster opportunities for you to learn and help the global open data community grow.
