In order to calculate the biorhythm and partner compatibility, I use the following equations:

- Physical biorhythm (indicator of the body's resistance to effort): sin(2 * π * t / 23) * 100 [%]

- Emotional biorhythm (stress resistance index): sin(2 * π * t / 28 ) * 100 [%]

- Intellectual biorhythm (indicator talking about mental capabilities): sin(2 * π * t / 33) * 100 [%]

- Physical compatibility: | cos(π * d / 23 ) | * 100 [%]

- Emotional compatibility: | cos(π * d / 28) | * 100 [%]

- Intellectual compatibility: | cos(π * d / 33) | * 100 [%]

where:

t: the number of days you have lived

d: the difference of days of life between partners.
