Show HN: Creating OCD versions of a yearly calendar

I'm a big fan of history's many attempts to square the circle: divide a hard to factorized number (days in a year) into even chunks, without sacrificing things like agricultural seasons.

This little project explores different calendar versions. I have highlighted my favorite solution :)

- 6 days / week - 5 weeks / month - 3 months / quarter - 4 quarters / year

As a good European the remainder 5 days are end of year holidays.

You can also select some of the historical attempts.
