One 38" x 25" vinyl chalkboard panel printed with gridlines. All you need to to is incribe the dates! 

The panel is repositionable on walls, wood, glass, and paper. It is easy to remove and won't harm most surfaces.

Write on it with chalk and wipe clean with a soft cloth. Chalk is included.

Please note: It is imperative that freshly painted walls be allowed to dry for a minimum of three weeks before applying wall adhesives, as the humidity may cause peeling.
