Look like we found another desktop toy, everyone. There is a online generator you can use to create a template of a 12 sided calendars which fits nicely to a pentagon dodecahedron. Not only it looks great, you can also use this as a dice, to decide when should you start your non-urgent tasks! ;)

Another favor you get is the rhombic dodecahedron style. More geeky feel. I still like the pentagon one.
