Abstract

A perpetual calendar (1) is formed by a flat blank (2) having a front calendar face (5). Segments (8) bearing monthly indicia and segments (9) with data indicia are provided on the front calendar face (5). A flat disc (12) is rotatably mounted behind the blank (2). The disc (12) has outer segments (16) with yearly indicia and inner segments (24) with week day indicia. The disc (12) passes through an associated slot (20) in the blank (2) for alignment of the yearly indicia in segments (16) with the monthly indicia in segments (8). A flap on the blank (2) resiliently engages a rear of the disc (12) as it passes through the slot (2) to retain the selected segments (8,16) in alignment. A cut-out slot (26) in the blank exposes the week day indicia of segments (24) which is aligned with the date indicia of segments (9).
