biorhythm
The classic three biorhythm cycles as sine waves of days-since-birth — a pure, deterministic entertainment/novelty pack.
Biorhythms are a pseudoscientific pastime. For entertainment only.
| Cycle | Period |
|---|---|
| physical | 23 days |
| emotional | 28 days |
| intellectual | 33 days |
Tools
| Tool | Args | Returns |
|---|---|---|
cycles | { birthDate, date? } | Values + phase for one day |
chart | { birthDate, startDate?, days? } | Daily series for plotting |
criticalDays | { birthDate, month } | Days a cycle crosses zero (YYYY-MM) |
compatibility | { birthDateA, birthDateB } | Cycle-alignment score |
Values are in [-1, 1]; percent is the rounded ×100 form; phase is rising / falling / critical (near a zero crossing). Day 0 (birthday) is 0 on every cycle.
