I feel that is my duty to post any decent perpetual calendars I come across, not only because they'll save you from 12 months of usually bland/bad photography, but also because they'll save you money (if you live long enough)...

"This thought-provoking calendar features an aluminum background with the months on one side; the dates on the other -- you simply stretch the band across from month to date to see the exact day."
