Zi Wei Dou Shu Calculation Variants
Compare calculators through input, boundary, school, table, and version evidence instead of judging screenshots.
Overview
Calculator differences become understandable when every chart carries normalized input and a rulebook stamp. The troubleshooting guide gives a field-by-field comparison sequence and distinguishes display variation from calculation variation.
At a glance
- Compare first
- Normalized time
- Then
- Lunar and palace anchors
- Rule layer
- School and tables
- Audit
- Version stamp

What this section covers
The guide catalogs input, boundary, school, table, engine, and display differences.
It shows how to isolate the first divergent field.
Use this hub when two charts differ: align raw birth input first, then effective time and calendar fields, palace anchors, star placements, transformation rows, and presentation.
- Use structured fixtures.
- Stop at first divergence.
- Open the first owner whose structured field diverges.
Comparison workflow
Align raw and effective inputs before checking palaces, stars, and transformations.
Then compare provenance and presentation independently.
A useful comparison fixture includes location, time zone and historical offset, calendar and leap-month status, year and Zi-hour boundary policies, rulebook version, and engine revision.
- Fields before screenshots.
- Rules before verdicts.
- Compare fields in sequence instead of judging screenshots.
OpenFate policy visibility
OpenFate stamps its engine, lineage, boundaries, time, leap-month, and transformation choices.
Historical charts should keep their original revision.
Every difference report should cite the rule or table responsible for the first divergence and say whether it is an input, calculation, school, version, or display choice.
- Version changes.
- Do not overwrite silently.
- Preserve the original chart provenance when policies change.
What comparison can establish
The checklist can explain why computed charts match or differ.
It cannot prove which interpretive tradition predicts reality.
Troubleshooting can explain why outputs match or differ; it cannot establish which symbolic interpretation predicts reality or authorize a consequential decision.
- Reproducibility is not validity.
- No high-stakes prediction proof.
- Treat reproducibility and empirical validity as separate questions.
