Dodecahedron Calendar

Here’s a fun use for a dodecahedron:  folding it up to make a yearly calendar!

Just download the PDF, print, cut, fold, and glue!  Access to a large-scale plotter might be nice, as the 8.5 x 11 version folds into something that’s pretty small.

It’s too bad there aren’t eight days in a week, otherwise we could put the octahedron to use, too!
