What a Zi Wei Dou Shu synastry reading actually compares

Zi Wei Dou Shu compatibility is not a single percentage. fateshow casts two complete charts from both birth moments and compares the palaces, stars, and transformations that traditional practitioners use to judge long-term fit, so every dimension score comes with 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 describes the partner you are wired to look for. Reading both charts together reveals whether the person in front of you matches that pattern, and where the expectation drawn from the chart differs from the relationship you actually have.
Birth-year transformations
The four transformations show how each person changes the other. A transformation landing in a supportive palace reads as momentum, while the same star landing in a strained palace reads as pressure that builds slowly instead of showing up in the first month.
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 birth moments

    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 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?
The birth details are used to calculate the charts and generate the report. No account is required until you decide to unlock the full report, and the calculation itself does not depend on storing the data.
