ABSTRACT:
A perpetual calendar has a cylindrical outer casing having several viewing apertures formed therein. The casing displays on an outer surface thereof in seven vertical columns the dates of the month from one to twenty-eight. One of the apertures is positioned to display up to three additional dates of the month after the numeral 28. An inner cylinder is rotatably mounted in the outer casing and coaxial therewith. This cylinder displays on an exterior surface thereof the 12 months of the year and also month ending date or dates for months having more than 28 days. This cylinder is rotatable to display the current month through one aperture and correct month ending date or dates for that month through another aperture. Also, a ring is mounted for rotation in the outer casing and is coaxial with this casing. The ring displays on its exterior surface data for indicating days of the week. Preferably the device is also capable of displaying through apertures of the casing data relating to zodiac signs for the indicated month.
