This on-line site is designed to accompany the HIDDEN WAVES audiocassette presentation created by Dän Lee Dimke, PhD. The Biorhythm Engine below, which requires a Java-capable browser, (Netscape or Internet Explorer 4.0 or higher) was designed by Jin Sato. You can use it to instantly chart your biorhythm wave form for today. To use the Biorhythm engine, first enter your Birthday, Year( YYYY), Month (MM) and Day (DD).

The Biorhythm engine defaults to the current date as the Target (Now) Date. So, once you've entered your birthday, just click the DISPLAY button to view your personal Biorhythm Chart. The black vertical line indicates today's date. The chart extends 10 days into the past and 30 days into the future.
