ABSTRACT:
A calendar including a first disk and a second disk. The second disk is connected to and rotatable concentrically relative to the first disk. The first disk includes a window and indicia adjacent to the window representing the various days of the week. The first disk further includes indicia indicating various months of the year and lead lines which function as pointers. Thus, the user may select, by using the pointers, a desired year from a table or a list of a plurality of years appearing on the second disk. This configuration allows the user to easily select a predetermined year by means of a pointer. The second disk further includes a day number grid, the dates ranging from 1 to 31. When the second disk is rotated relative to the first disk, the day grid draws an orbit and the grid is located below the window of the first disk. Consequently, when a predetermined year with respect to a predetermined month is selected, the window displays a corresponding calendar month. A stand is provided for supporting the calendar. A click stop, rachet wheel and leaf spring assembly may be provided behind the second disk, for controlled, incremental movement of the second disk relative to the first disk.
