Download a 12 sided calendar

Download a dodecahedral calendar. You may choose between PostScript and PDF format. Choose PostScript format if you want to mark holidays and birthdays. The PostScript file explains how to do it.

Calendar on a regular dodecahedron

Once upon a time I made a PostScript program to print templates for generic polyhedra called polyeder.ps. This program was posted to comp.lang.postscript after a request for this kind of program. Andrew Rogers added code to polyeder.ps and turned the dodecahedron into a 12-month desk calendar and posted it to comp.sources.postscript.

I've made a few changes to Andrew Rogers' deskcal, and wrapped it into a script to make it more available for people without knowledge in PostScript.

Hints for calendar on a regular dodecahedron

• Regular printer paper (80 g/m²) will be fine, but heavier paper (100-120 g/m²) will result in a more robust calendar. Do not use even heavier paper (160 g/m²).
• Do all folding after cutting
• Glue the tabs matching the untabbed face last (November).

Calendar on a rhombic dodecahedron

I have reused Andrew Rogers' calendar generator, so you can get calendars on Nick Robinson's rhombic A4 units, and make a rhombic dodecahedron calendar. This variant is made without glue.

Hints for calendar on a rhombic dodecahedron

• Print the calendar on regular A4 paper (80 g/m²).
• The rhombic calendar will not fit on American letter paper :-(
  It will fit on American legal paper, but then you have to cut off the extra paper.
• Print the calendar on 12 sheets of paper with different colors to get a more colorful calendar.
• Fold each piece into a rhombic unit as shown below.

• Join the rhombic units as shown on the pictures below
