My Secret Santa caught on that I like photography and got be this beautiful calendar! Thank you so much!

I'm going to be honest, I'm not sure how it's supposed to work. It's individual 3x5 photographs. I can't really use it as a desk calendar, or write on it, so any tips are helpful!

EDIT: Thanks for the awesome ideas for my calendar guys! I haven't settled on which one to use, but I've got some time. :)
