This listing is for 1 wooden perpetual calendar. We always put a calendar for the current month in an area that the kids are able to see the date. My son has learned a little more about recycling & he asked about the calendar & recycling. We wanted to make something that fit our style & was still easy for the kids to use & this is what we came up with! A circular spinning perpetual calendar. This hangs from the wall like a picture would on a nail or a screw. The rings turn manually so there are no small parts to break. The outter most ring is 11.5 in diameter so this is a substantial size. It's made with cherry for the rings, maple & poplar for the dial window. Its 12 3/4 tall & 1 5/8 thick.
