Two-Person BaZi Compatibility (Synastry)

A BaZi compatibility reading for any two people — romance & marriage (the classical 合婚), boss & subordinate, business partners, friends or family. Five relationship presets share the same four-tier grade and six dimension details; only the reading emphasis and advice adapt. Both sides are equal roles (Partner A / Partner B); everything computes in your browser and the birth data never leaves it.

All five presets share the exact same scoring and grade bands — a preset only shifts which dimensions lead the reading and the advice copy, never a single score.

How well two partners fit — the classical synastry question: do the five elements complement, do the day pillars combine, do the long-term rhythms run in step?

Partner A
Partner B

Gender only steers each side's decade-fortune direction in the chart math — it never affects the grade or the wording.

Methodology — weights in the open

The six dimensions carry public weights summing to 100. The weighted result maps onto four grade bands only: Superior (≥75), Favorable (55–74), Moderate (35–54), Needs mindful effort (<35). No numeric score is ever displayed — competitors keep this black-boxed; we publish it instead.
