Although I have calendar apps on my phone, as well as one for the whole family, I use this calendar every year. It is kept in the kitchen on a wall where we can all see it at a glance. Sometimes, it's just good to go the old school way by having a wall calendar. One never knows when an electronic device will die! :-) The calendar is big and very colorful, and I like using some of the stickers, especially the birthday ones!
What I don't like about the 18-month calendar is that I don't ever get to use the entire calendar. I admit that it worked great when I was in the classroom because I had the school year at my disposal. However, it always seemed weird not changing the calendar on New Year's Day. I prefer a 12-month calendar that starts on January 1.
