-26- IMPROVED PERMANENT CALENDAR Abstract of the Disclosure An improved permanent calendar assembly adaptable to display any month of any year. The construction includes a flat main body with forwardly protruding tracks for removable mating with date columns. For flexibility of display, blocks or end pieces carrying one of the dates "29", "30" and "31" on one surface and a blank on an opposed surface are rotatably or removably mounted onto the date columns so that either side of any of the blocks may be selected for display. The calendar also features a construction that allows easy removal and rearrangement of the vertical date columns and yet prevents their disengagement when, for example, when the calendar is tilted forward. At least one lipped horizontal track extends across the date column area. Defined in the 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 with surfaces facing in more than one direction and particularly with an engaging surface which has surface normals with no upwardly directed component. This engaging surface mates with an opposed surface in each date column groove when the calendar is tipped forward to prevent the date column from falling. A support stand is pivotally secured within a cut out in the back wall of the calendar frame. A compressing spring is positioned in the body to bias the stand into frictional engagement with one of the side walls of the cut out so that it will not move from a position in which it is placed..
