How BaZi marriage compatibility works

01

Enter two charts

Each person's birth date and time. Charts are cast locally in your browser — nothing is uploaded.

02

Read the five dimensions

Communication, emotion, values, long-term stability, passion — every dimension backed by evidence.

03

Get things to practice

Where it flows, where it needs work, with actionable suggestions — a portrait, not a verdict.

Why you can trust it

Deterministic engine

The same two charts always produce the same scores, and every conclusion points back to a specific signal — anti-Barnum, no lines that would fit anyone.

Hard red lines

No verdict on whether you "match", gender-symmetric language, and we never write fatalistic labels like "harms-husband / harms-wife" or "zodiac mismatch".

Charts cast locally

Both people's birth details are computed into Four Pillars locally in your browser — never uploaded to third-party servers.

FAQ

Does a low compatibility score mean we are incompatible and should break up?+

No. The score is a relationship portrait — it shows where things flow and where they need practice, never a verdict on whether you "can be together". Low dimensions are written as practicable homework with a next step; we never advise you to stay or to leave.

Will this tool say "harms-husband", "harms-wife" or "zodiac mismatch"?+

Never. Those are fatalistic verdicts that cause real harm — people have been pressured by family into breakups and depression over a "zodiac mismatch". We hold hard red lines: gender-symmetric language, no preset relationship roles, and we only talk about relationship dynamics and things to practice.

How is the compatibility score calculated?+

Five dimensions (communication / emotion / values / long-term stability / passion) are each weighted from concrete signals: the Ten-God relation between the two Day Masters, element complementarity, spouse-palace combinations and clashes, and luck-cycle synchronization. Every conclusion points back to a specific fact — no vague one-size-fits-all lines.

Why is our score only moderate when the description says we are strongly attracted?+

Because the engine is honest. A "Water × Fire" pairing, for example, can score high on emotional passion yet need work on communication, so the total lands mid-range. We give a truthful portrait, not a flattering perfect score.

How is this different from the synastry tool?+

Compatibility handles romance: two people paired symmetrically with a match score. The relationship map (synastry) covers everyone else — it finds your benefactor zodiacs, then lets you add parents, friends, colleagues and business partners, one relation card each. Use compatibility for a partner, the relationship map for everyone around you.
