## Biorhythm Calculator

A biorhythm (from Greek βίος - bios, "life" and ῥυθμός - rhuthmos, "any regular recurring motion, rhythm" is an attempt to predict various aspects of a person's life through simple mathematical cycles. The theory was developed by Wilhelm Fliess in the late 19th century, and was popularized in the United States in late 1970s.

According to the theory of biorhythms, a person's life is influenced by rhythmic biological cycles that affect his or her 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, and by modeling them mathematically, it is suggested that a person's level of ability in each of these domains can be predicted from day to day. The theory is built on the idea that the biofeedback chemical and hormonal secretion functions within the body could show a sinusoidal behavior over time.

Most biorhythm models use three cycles: a 23-day physical cycle, a 28-day emotional cycle, and a 33-day intellectual cycle. Although the 28-day cycle is the same length as the average woman's menstrual cycle and was originally described as a "female" cycle (see below), the two are not necessarily in any particular synchronization. Each of these cycles varies between high and low extremes sinusoidally, with days where the cycle crosses the zero line described as "critical days" of greater risk or uncertainty.

The numbers from +100% (maximum) to -100% (minimum) indicate where on each cycle the rhythms are on a particular day. In general, a rhythm at 0% is crossing the midpoint and is thought to have no real impact on your life, whereas a rhythm at +100% (at the peak of that cycle) would give you an edge in that area, and a rhythm at -100% (at the bottom of that cycle) would make life more difficult in that area. There is no particular meaning to a day on which your rhythms are all high or all low, except the obvious benefits or hindrances that these rare extremes are thought to have on your life.

In addition to the three popular cycles, various other cycles have been proposed, based on linear combination of the three, or on longer or shorter rhythms.

Biorhythm curves describe very well the energy levels and the capacity for performance on 3 Primary levels: physical, emotional and intellectual.
The intellectual biorhythm lasts for 33 days and relates to your mental capabilities, creativity, aptitude to solve problems.
The emotional biorhythm lasts for 28 days (just like the Moon's cycle) and relates to your emotional stability or stress.
The physical biorhythm lasts for 23 days and is related to your physical energy, strength, health, stamina.

Secondary rhythms: Spiritual (53 days), Awareness (48 days), Aesthetic (43 days), Intuition (38 days)
