Abstract
A perpetual calendar has a free standing or wall hung structure supporting an anchor point and a number of concealed magnets. A pointer magnet is attached by a line to the anchor point. Attraction between the pointer magnet and a selected one of the concealed magnets can support the pointer magnet and line in levitation against gravitational pull. The concealed magnets may be arranged in an arc on the calendar structure, with day, month or year data indicated along the arc at locations corresponding to the concealed magnet locations, so that the line and pointer magnet serve as a visual indicator of selected calendar data. Multiple displays of calendar data may be provided on a calendar structure, including multiple levitated pointer displays or combinations of levitated displays and sliding pointer displays.
