This is a set of 16 calendar pieces plus holiday pieces. There is a set for each month of the year plus 4 extras (including zoo animals, fish, apples, and school). The holiday pieces include most of the U.S. national holidays along with birthday pieces as well.
I bought a cheap wall or desk calendar from the dollar store and had it laminated. I then made all these calendar pieces and laminated them as well. It gave a plain old calendar lots of pizzaz!
