Direct answer
A useful BaZi compatibility comparison does not reduce two people to one score. It compares each person’s Day Master, seasonal context, Ten God functions, and active luck cycles, then turns overlap and friction into concrete relationship conversations.
Read it in this order
Calculate both charts independently with the same disclosed calendar rules. Compare patterns after each chart is stable, and distinguish a natal interaction from a timing interaction. Unknown birth time should limit any Hour-Pillar comparison.
From symbol to real life
Use the comparison to discuss boundaries, money, care, autonomy, and conflict repair. Compatibility never outweighs consent, safety, behavior, or direct communication, and it cannot guarantee whether a relationship will begin or last.

See my relationship structure →Worked example: two charts, no compatibility score
Imagine Person A has a Jia Wood Day Master with strong Resource support, while Person B has a Xin Metal Day Master with visible Output and firm Authority themes. Metal controlling Wood is not enough to label the relationship. Each natal chart must first be stable; then the comparison asks how standards are communicated, how support is received, and whether active luck cycles amplify pressure or create room for repair.
Turn symbolic tension into a real conversation
The useful output is a conversation map: how each person handles time, money, autonomy, care, and conflict repair. One partner may experience frequent advice as support while the other experiences it as control. That hypothesis can be checked through behavior; it is not proof of compatibility or incompatibility.
- Calculate both charts independently with the same calendar policy.
- Compare Day Master functions, Day Branch context, and element exchange without collapsing them into a score.
- Separate natal patterns from temporary Da Yun or annual pressure.
- State what cannot be concluded when either birth time is unknown.
Method, sources, and editorial review
This page follows Ziheng’s public calculation rules. Traditional vocabulary is cross-checked against commonly used frameworks associated with Yuan Hai Zi Ping, San Ming Tong Hui, and Di Tian Sui; no paragraph is presented as a verbatim classical quotation. Calculation, traditional interpretation, and practical action remain separate.
What this cannot do
This method cannot guarantee wealth, health, legal, work, or relationship outcomes. It is for cultural reflection and planning questions; major decisions still require real evidence and qualified advice.
FAQ
Can BaZi compatibility predict marriage success?
No. A two-chart comparison can reveal symbolic overlap and friction, but it cannot predict marriage success or replace communication, consent, safety, shared values, and observed behavior.
How does Ziheng handle disputed judgement?
Balance, climate, and structure evidence stay separate; a primary direction appears only when at least two lenses agree.
