Abstract
An improved permanent calendar assembly is disclosed which is 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, end pieces carrying one of the dates '29', '30' and '31' on one surface and a blank on an opposed surface are rotatably or pivotally mounted at the bottom of the date columns so that either side of any of the end pieces 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 calender is tilted forward. At least one lipped horizontal track extends across the rear of 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 a surface that mates with an opposed surface in each date column groove when the calendar is tipped forward to prevent the date column from falling.
