This looks great, but for anyone more digital based: does anyone here know of an open calDAV (or similar) atronomical calendar? Would be awesome to sync these into say, a calendar progamme, but I only know of google calendar type proprietary ones.

I use this one, it's free and you can filter event type and location: https://in-the-sky.org/newscalyear.php

I have one for my iCloud account that sets entries for various astro events. I subscribed to it years ago, so I don't have a clue as to where/when I came across it. I have no idea how it was built, so no info on calDAV or not.

Anyone more familiar with calendar subs that could offer insight to find out how I can trace this back?
