Always know the month, day, and day of the week with a perpetual calendar on display! You can use it year after year! The concentric circular design will be the focal point for any room you would display it in. This item makes a great gift for teachers, children, and businesses! A "perpetual calendar" gives the date, day, month while automatically taking the number of days in the month, and the cycle of leap years. It is a masterpiece of architecture and miniaturization. The calendar is approximately 13 inches tall by 12 inches wide and approximately a half inch thick and ships with a display stand. Personalize the center piece with a graphic and/or text. A business logo or a name would be the perfect addition to make this calendar truly unique. This item ships with the calendar and a display base. The display base ships disassembled (but is very easy to put together)! Give someone the gift of time!
