A child\s learning calendar is set forth to enable a child\s association of various shapes and recognize same and simultaneously gain understanding of the sequence and passage of days of the week. The calendar includes seven pairs of matched cards associating a day of the week with a predetermined configuration wherein the cards are each formed at respective engaging edges with extended elecrical contacts whereby positioning of the appropriate and predetermined matched pairs of cards within a pair of overlying compartments, the proper positioning of electrodes will complete an electrical circuit to illuminate a light bulb pair to indicate proper matching of the cards.
