## Community Calls
Community Calls are quarterly meetings that feature updates and presentations on OME-Zarr specification work, tooling ecosystem, and use cases. **Everyone is welcome** to these calls - developers, users, and enthusiasts alike. Whether you have just heard about OME-NGFF and are curious to learn more or if you have been working with it every day, consider yourself invited.

We host Community Calls **quarterly at 9:00 CET and 17:00 CET**. The same agenda is repeated in both time slots to allow participants around the globe to choose the one that fits their schedule best. Get in touch with [Virginie Uhlmann](mailto:virginie.uhlmann@mls.uzh.ch) if you would like to present at an OME-NGFF Community Call.

Community Calls are added to the above calendar and announced on [image.sc](https://forum.image.sc/tag/ngff-community-call):
