Abstract: A gestation calendar for use by an expectant mother. A first disk has first indicia corresponding to days of a calendar year. A second disk is pivoted concentrically to the first disk and has second indicia defining successive weeks of a gestation term and associated information. The information includes imagined statements by a fetus representing its development during the time intervals, with corresponding information relating to prenatal health care for the mother. When the first and the second disks are positioned so that an index mark of the second indicia is aligned with a start date of the mother's last period in the first indicia, the development of the fetus at a certain date during pregnancy along with the corresponding prenatal health care information are conveyed by the information associated with that time interval which is aligned with the certain date in the first indicia.
