The biorhythm calculator, the freeware program

This program is to illustrate the theory described below. You can use this online software for non-commercial purposes to calculate, create and print the chart of biorhythms for free. You don't need any download or installation on your computer. The calculation is done in hourly increments without guarantee for correctness. Your data (date of birth, month to calculate and free text) will not be sent over the Internet by the program and can therefore never be stored externally or otherwise evaluated.


The operation of the free online software to calculate the chart

To begin, please select the appropriate date and hour of birth in the drop-down fields of the biorhythm calculator. If you don't select a special hour, the software takes this as 12pm (noon). After first calculation you can use the arrow buttons as well as the arrow keys to move the month of calculation back or forward.
Use the printer icon to get a scaled output on your printer.
The string -'``'-.,_,.- can be changed. For example, you can type in your name before printing the chart.


The idea: the biorhythms affect your health

The biorhythm is a scientifically unproven theory that says that you can calculate good and bad days in your health. The doctrine is based on three sinus curves with different cycles:

These biorhythms begin at birth at zero and initially runs into the positive range. All crossings of the zero line are critical, and therefore potentially bad days on which, if possible, no increased risk activities should take place. High and low points of the curves are particularly suitable or unsuitable for the corresponding activities.
The basis for this calculation was created at the beginning of the 20th century by the Viennese psychologist Hermann Swoboda and the Berlin physician Wilhelm Fliess.
