ABSTRACT:
An improved permanent calendar assembly adapted and structured to display any month of any year. As in known calendars of this type, the construction features a flat main body with forwardly protruding tracks for removable mating with date columns. For flexibility of display blocks or end pieces carrying dates "29", "30" and "31" are rotatably or removably mounted onto the date columns. The date mounting structure allows both sides of the blocks to be shown, one side carrying a date and the reverse side being blank.
