rubike28099s-cube-perpetual-calendar-picture-1Well, this Rubik’s Cube Perpetual Calendar is not a calendar that everybody will like. Because you need  “solve” it and get the date set. So everyday you will have to tweak your brain in order to get it set. Sometime, the time you probably get it correctly set nearly time to set it again. So if you not a Cube expert, it will be your daily headache.
