@icefox I have one of those as well, but for religious purposes, I wanted a twelve/seven/four division on this one. I could bite the bullet and skip the intercalendary days in favor of a full leap month, bug I suspect the math for that will be obscene if I want the same accuracy.
The Lapinian Civic is a 13/4/7 with a leap week; that was my first discovery.

@icefox I've also got a true lunar Equestrian Nightmare calendar using nested 21/8 metonic cycles and an alternating 29/30 month lengths. I need to write that one back up and validate the maths.
