If you do not feel like gluing and if you do not plan to use your calendar as wall calendar you could use a gift box as a calendar holder. Instead of tearing off a page every day you can just move it to the back of the stack. All pages will be in the box and you can enjoy them at any time.
Use a gift box with dimensions 5.5 inch/3.5 inch/1 inch. This is a standard size gift box, available in various colors and patterns in the stores.
Use the gift box cover as a base and the box itself as an easel stand.
Place the calendar sheets on the box cover and adjust the angle of the easel stand (box).
