Borrow a cute idea from the Dutch and get a birthday calendar. Unlike a traditional calendar, a birthday calendar doesn’t have the days of the week on it so it can be used in perpetuity. The idea is that you write important dates on it and use it year after year. Apparently you’re supposed to hang it in your bathroom, but really, any spot in your home that you frequent is probably fine. (If you search Etsy for “perpetual calendar” or “birthday calendar,” you’ll find several options.)
