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 and he asked about the calendar and recycling. We wanted to make something that fit our style and was still easy for the kids to use and 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 and poplar for the dial window. Its 12 3/4 tall and 1 5/8 thick.
