Fun calendar project “A dodecahedron is literally a polyhedron with 12 faces, but usually a regular dodecahedron is meant: a Platonic solid composed of twelve pentagonal faces, with three meeting at each vertex. It has twenty vertices and thirty edges. Its dual polyhedron is the icosahedron. Download a dodecahedral calendar after your own specifiation. Choose PDF format if you can’t print PostScript files. Choose PostScript format if you want to modify the calendar. The PostScript file explains how to mark holidays and birthdays.” Thanks Star! Link.
