Biorhythm Calculator
Enter the Year, Month and Date that you were born in the three boxes (tab keys will not work, so you must click in each box), then click on the Calculate button. Your cycles will appear on the chart, a dark BOLD line indicates today's date, and then 30 days after today's date appear on the chart. Red/blue lines indicate weekend days. Transition (critical) days occur whenever a cycle crosses the dark HORIZON line that runs from left to right across the middle of the chart. After clicking on Calculate your biorhythms will appear as well as the number of days you have lived at the top of the chart. You can selectively turn off the Physical, Emotional or Intelletual lines at this point by clicking the checkboxes at the upper right of the chart.
  • PHYSICAL: The physical rhythm cycle is the shortest with a duration of 23 days, it is responsible for strength, stamina, drive, confidence, energy, aggressiveness and courage.
  • EMOTIONAL: The emotional rhythm cycle lasts for 28 days and determine your moods, optimisms, cheerfulness, creativity, well-being and your emotional sensitivity.
  • INTELLECTUAL: The intellectual is the longest rhythm cycle, lasting 33 days and it influence your powers of reason, perception, acuity, judgement, decision-making and common sense.
  • Fundamentally biorhythms are a way of expressing continuous changes, which can help you plan your life more effectively if you can come to understand them and how they influence you. Each rhythm begins on the day you are born and follows its course throughout life and stops at your death. Everyone is subject to their influence and most likely can feel them, though some people will not conform to the established patterns at ALL times, most people can recognize a trend of rhythmic patterns in the Emotional, Physical and Intellectual physiology.

    Each rhythm has two stages (or phases), positive or high on the chart, and negative or low on the chart. The day of transition from one phase to the other is called a critical day, and they are very important, for it is then that we are most prone to accident, instability and error. During the days of transition (critical days) we become vulnerable, off-balance and our normal reactions are slowed down. This period may last for up to 48 hours, so it is important to be aware of when these critical days are going to occur so that you can plan ahead and effectively make an adjustment.
