Would your city, municipality or company like to take part in this year’s Earth Night (19.09.25) – i.e. switch off the light visible in the open air for an entire night – and officially announce this?

We will be happy to publish your participation registration on this website under the menu item “We are taking part”. Publication in our participation directory is free of charge.

The corresponding online form will be available here on this website from April 1, 2025.

Until then, we wish you a good time and the darkest night skies possible.
