I saw this great calendar reproduced in a book—it's worth opening the image in another tab to see it more clearly—

A lovely calendarThe book

—and loved its vibe, so, I made one! You can just print this page. It comes out at 11×17, and without this note on top, of course.

The original calendar was designed by Heini Fleischhacker for Herman Miller in 1971.

This one is generated by code, so if you'd like to make a calendar for 2020, or change the way it looks, you can go over to the Glitch page and edit to your heart's content.
