Biorhythm Application Please notice that this is not a solid science yet.

According to believers in biorhythms, a person's life is influenced by rhythmic biological cycles that affect one's ability in various domains, such as mental, physical and emotional activity. These cycles begin at birth and oscillate in a steady (sine wave) fashion throughout life.Most biorhythm models use three cycles: a 23-day "physical" cycle, a 28-day "emotional" cycle, and a 33-day "intellectual" cycle. "critical days" might have greater risk or uncertainty. Input your birthday to calculate your biorhythm. Because a birthday might be a little different than a expected date of birth, you might need to "calibrate" your birthday based on your observed "best day" and "critical day". This report uses a 66-day period. Today is at the center of this plot.
