This is a re-post of a puzzle I wrote for the 2021 Mathcamp Puzzle Hunt. The difficulty is 5/10 or so (easier than the first puzzle I wrote for this blog, but harder than the second). If you haven’t done these sorts of puzzles before, I recommend starting with e.g. this one or this one instead.
Click the link below to open the puzzle. If that doesn’t work, here’s another link.
This puzzle was featured in the Earth round of an Avatar: The Last Airbender themed hunt, so don’t read too much into the word “earthly” in the title (it’s mostly there to fit the theme).
Good luck and have fun! I’ll probably post hints and a solution sometime soon.

I cannot seem to download the puzzle, is there another place where I can get a copy?

Huh, strange. This link doesn’t work? https://hunt.mathcamp.org/puzzles/static/2021/earth/calendar/%5BMCSPH%202021%5D%20A%20More%20Earthly%20Calendar.pdf
(If it doesn’t, I suspect you’re having problems with your PDF viewer.)
