What a Zi Wei Dou Shu synastry reading actually compares

Zi Wei Dou Shu compatibility cannot be reduced to a single percentage. fateshow casts a complete chart for each person from their birth details and compares the palaces, stars, and transformations that traditional practitioners use to assess long-term compatibility, so every dimension score includes the palace and star evidence behind it.

The five dimensions behind every score

Life Palace branches
The Life Palace branch describes your natural pace and the way you meet the world. Comparing two branches shows whether one person consistently sets the tempo while the other adapts, or whether the rhythm can stay balanced over years rather than weeks.
Spouse Palace mirroring
The Spouse Palace is traditionally associated with the qualities and relationship patterns you may seek in a partner. Reading both charts together can highlight where those patterns align with—or differ from—the relationship you actually have.
Birth-year transformations
The Four Transformations are used to explore how each person may affect the other. A transformed star in a supportive palace may suggest momentum, while one in a more challenging palace may point to pressure that develops over time.
Five-Element Bureau
The Bureau sets how each chart prefers to operate in practical life. When two Bureaus pull in different directions, everyday decisions about money, housing, and work quietly absorb more energy than either person expects.
Life Palace stars
Major stars in the Life Palace shape communication and decision-making. Comparing them shows whether disagreements resolve through discussion or through one person repeatedly giving way to keep the peace.

How the comparison is calculated

  1. 1.Enter both sets of birth details

    Date, time, and place for each person. The birth hour matters because it determines the Life Palace and therefore the structure of every other palace.

  2. 2.Two charts are cast independently

    Each set of birth data is converted to the Chinese lunar calendar and calculated on its own, using the same engine that powers the personal Zi Wei report.

  3. 3.Scores are read against the palaces

    The five dimensions are computed from palace positions, star placements, and birth-year transformations, and each score is displayed together with the evidence it came from.

Frequently asked questions

Is a Zi Wei Dou Shu synastry score scientifically validated?
No. It is a traditional Chinese astrological method, and the score is deterministic given the birth data rather than statistically validated. Treat it as a structured way to think about a relationship, not as a prediction.
What if I do not know the exact birth hour?
The hour determines the Life Palace, which shifts every other palace with it. Without a reliable time the reading becomes far less specific, so it is worth checking a birth record before relying on the result.
How is this different from Western astrology synastry?
Synastry compares planetary positions between two charts. Zi Wei Dou Shu compares twelve palaces, more than a hundred stars, and the birth-year transformations, and it is read against Chinese calendrical rules.
Do you store the birth details I enter?
We use the birth details you enter to calculate both charts and generate the report. You do not need an account for the free preview; you only need to sign in if you choose to unlock the full report.
