Abstract: A hand-held gestational computer comprises a microprocessor programmed to receive input signals representing the current date and at least one parameter is selected from the group consisting of the date of the first day of the last menstrual period, estimated gestation age, conception date, estimated date of confinement by ultrasound analysis, and estimated fetal weight. The microprocessor produces output signals representing the value of at least one parameter selected from the group consisting of estimated gestation age, estimated date of confinement, conception date, estimated fetal weight, and the percentile of the estimated fetal weight for the estimated gestation age. There is a palm-sized housing for the microprocessor, a display and one or more pushbuttons for sequentially selecting different display fields in which data is to be entered, and sequentially displaying data available for entry in the selected display field.
