The calendar of the normally folded type is displayed in an unfolded position on a backboard upon which is pivoted a frame. The frame has upper and lower openings defined by stiles and crosspieces. The back of the frame has a recess sized to receive the calendar in its unfolded position. The openings in the frame permit viewing of the upper and lower calendar sheets when positioned therein. When the frame is closed against the backboard, the calendar is held in position with access to both the upper and lower calendar sheets. The frame is easily opened for adjusting of the calendar sheets.
