AstroZen BaZi Calculation Rules and Limits

01

Current calculation pipeline

AstroZen resolves the place, interprets the historical local time, calculates a location-aware solar-time correction, constructs the Four Pillars through a deterministic calendar library, derives relational fields, and only then prepares evidence for interpretation.

• Required: birth date and a resolvable place.
• Optional but material: exact local birth time and minute.
• Recorded: coordinates, IANA zone, UTC offset, adjusted time, and limitations.
• Separated: calculated fields, traditional labels, and AI-assisted prose.

02

Published rule table

The current engine uses solar-term calendar operations for Four Pillars, a longitude-plus-equation-of-time correction, weighted hidden stems for element statistics, and seasonal evidence for balance analysis. These implementation choices are versioned and testable.

03

Interpretive boundaries

BaZi is a traditional symbolic system, not a scientifically validated diagnostic or predictive method. AstroZen's calculations can be internally tested; the symbolic meaning assigned to those values is interpretive and should be presented as reflection rather than fact.

• No guaranteed personality, health, wealth, relationship, or future outcome claims.
• No forced equivalence between Five Elements and Western elements.
• No invented hour, Ascendant, house, or fast-moving placement when time is unknown.
• No use as a substitute for professional medical, legal, financial, or mental-health advice.

04

Versioning and reproducibility

A useful method page must change when the engine changes. AstroZen pairs source-controlled tests with a dated public dataset and records calculation notes in the report context. Readers can inspect the rule without needing access to a customer's private record.

Method note: The Accuracy Lab dataset is intentionally small. It demonstrates high-risk boundaries and output contracts; it is not a complete validation corpus for every historical jurisdiction.
