ABSTRACT:
A multi-dimensional calendar (10) for indicating the day, date and month. The multi-dimensional calendar (10) includes three disks (28), (30) and (32). The first disk (28) has a circumference and includes indicia indicative of the date printed about a periphery thereof. The second disk (30) has a circumference of a size smaller than the circumference of the first disk (28) and includes indicia indicative of the month printed about a periphery thereof. The third disk (32) has a circumference of a size smaller than the circumference of the second disk (30) and includes indicia indicative of the day printed about a periphery thereof. A platform (12) retains the first, second and third disks (28), (30) and (32) thereon, whereby the second disk (30) is positioned between the first and third disks (28) and (32). A first gear apparatus (64) automatically rotates the first disk (28) a first predetermined distance after expiration of a first predetermined period. A second gear apparatus (68) is connected to the first gear apparatus (64) for automatically rotating the second disk (30) a second predetermined distance after expiration of a second predetermined period equal to a period in which the first disk (28) completes a full rotation. A third gear apparatus (66) automatically rotates the third disk (32) a third predetermined distance after expiration of the first predetermined period. The current day, date and month is indicated on the calendar (10) by a pointer (36) having a window (40) below which the current day, date and month are aligned.
