ABSTRACT:
An improved permanent calendar construction that allows easy removal and rearrangement of vertical date columns and yet prevents their disengagement when, for example, the calendar is tilted forward. Extending horizontally across the date column area or well, there is located at least one lipped horizontal track. Defined inthe back wall of each date column are at least two openings or grooves that can mate with the track, as desired. The lip results in a track which extends in more than one straight axial direction and thus engages the groove at least in dual directions (and with the end portion of the track furthest from the back wall terminating in an upwardly and perpendicular direction from an axis perpendicular to the back wall). An example of the preferred embodiment is a track with a right angle lip. Of course, at a minimum, the purposes of the present invention can be accomplished if the track is not lipped and is parallel to or diagonally upwardly directed toward the rear wall.
