Hello,
An open enhancement request for the popular Nextcloud server is to be able to add national holiday calendars to the calendar sub-system. I recently discovered the page here with user-contributed calendars for Lightning. I downloaded the ICS file for my region and imported it into both Thunderbird and my Nextcloud server. This works very well. I posted this as a provisional solution on Github and got some positive reactions.
First, I would like to thank you for publishing these files – and the users for creating them!
Second, did you know that they are quite useful for other applications, such as Nextcloud?
If anyone is interested, please see the Github issue where the possibilities for promoting this helpful resource within the Nextcloud community are being discussed.
