How many do you have? What are they? I have a 2008 Miami calendar and Rockets calendar at work. At home, I have a 2008 Puerto Rico calendar.
I've got a golden retrievers calendar at home, a golden retrievers daily desktop calendar at work, and the Rockets game schedule calendar at work.
I have a plain office planner at work, and on the fridge at home I have a International Space Station Calendar you can download here: http://www.nasa.gov/mission_pages/station/main/index.html
A Vietnamese calendar someone gave me. I don't know any of the words on there, but the girls are cute.
