Abstract: A Biorythms analog computer-calendar is provided to display without computations the level of the physical, the emotional, and the intellectual biorythms of a human body. The level of the three biorythms appears on display in analog and digital forms for any dialed calendar date, if the computer-calendar is set initially with the individual's birth date. The analog elements used to register the three biorythm levels are drums attached to gears with a number of teeth equal or proportional to 23, 28 and 33, or to the period of the three biorythms respectively. A calendar arrangement is introduced to create a correlation between the displayed biorythm levels and the calendar date associated with them.
