For a while in the late 70s, the pseudoscience of biorhythms was popular enough to rival astrology, with kiosks in malls that would give you your weekly printout. It was also a popular entry in "Things to Do with your Pocket Calculator" lists. You can read up on the history at [https://en.wikipedia.org/wiki/Biorhythm_theory Wikipedia], but the main takeaway is that unlike astrology, the math behind biorhythms is dead simple. |

It's based on the number of days since your birth. The premise is that three cycles of unspecified provenance govern certain aspects of everyone's lives – specifically, how they're feeling physically, emotionally, and mentally. The best part is that not only do these cycles somehow have the same respective lengths for all humans of any age, gender, weight, genetic background, etc, but those lengths are an exact number of days |

And the pattern is in each case a perfect sine curve. Absolutely miraculous! |

To compute your biorhythmic profile for a given day, the first thing you need is the number of days between that day and your birth, so the answers in [[Days between dates]] are probably a good starting point. (Strictly speaking, the biorhythms start at 0 at the moment of your birth, so if you know time of day you can narrow things down further, but in general these operate at whole-day granularity.) Then take the residue of that day count modulo each of the the cycle lengths to calculate where the day falls on each of the three sinusoidal journeys. |
