Abstract: A method for operating an electronic apparatus so as to produce an automated display of date and time specific biorhythmic acupuncture points is disclosed. The method monitors a current Gregorian-calendar date and time generated by the electronic apparatus, converts it into a Chinese-calendar Kan-day and Chih-period index affiliated with a biorhythm, utilizes the index to indicate and retrieve a biorhythmic acupuncture point from a table of predetermined biorhythmic acupuncture points, and displays the retrieved biorhythmic acupuncture point and current date and time. Once started, the method continues to display and update current date and time and their corresponding biorhythmic acupuncture point until it is interrupted by a user of the electronic apparatus.
