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 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?

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

This looks perfect! Thanks!!

This is a block from where I work! MSU's Abrams Planetarium has been a mainstay of the Lansing community for decades and does awesome shows for astronomy fans of all ages! If you get a chance to visit I highly recommend it!

What a great piece of visual information design. Another favorite of mine from astronomy is the year poster that sky and telescope publishes every year: https://shopatsky.com/products/2025-skygazers-almanac-wall-p... And Kim Long’s (The Moon Book) yearly moon calendar: https://theexperimentpublishing.com/catalogs/summer-2024/202...
