The conceptionday greeting card includes a card member having at least one wall; and a conceptionday calculation wheel rotatably mounted on the at least one wall. The conceptionday calculation wheel includes an outer peripheral wheel section having first indicia thereon in the form of months and calendar days; and the calculation wheel also includes an inner wheel section rotatable relative to the outer peripheral wheel section; the inner wheel section having second indicia thereon in the form of a birth date marker and a conception date marker. Rotation of the birth date marker of the inner wheel section relative to the outer peripheral section is used to indicate the birth date of the user for determining the conception date of the user from the conception date marker of the inner section of the calculation wheel.
