01
Chart facts first
The Four Pillars, Day Master, element balance, and timing notes belong to deterministic code so the same input produces the same facts.
Four Pillars chart shell
Free BaZi Calculator
Start from birth details and keep chart facts separate from interpretation. The calculator workspace is ready for the deterministic engine that follows in the next implementation phase.
MVP status: public page, SEO metadata, trust copy, and save-path framing are live; chart calculation is wired in Phase 3.
Calculate a BaZi chart
Enter the minimum birth details for a deterministic Four Pillars draft.
02
Interpretation second
Narrative reading can explain patterns, tradeoffs, and next actions, but it cannot silently rewrite calculated chart data.
03
Private by default
Birth data and saved profiles are kept out of public crawler files, share previews, and generated SEO surfaces.
Planned calculator flow
01
Enter birth details
Date, time, and location inputs will keep uncertainty explicit, including unknown time and boundary-sensitive cases.
02
Calculate stable facts
The shared engine will produce pillars, element balance, and trace notes before any generated interpretation appears.
03
Save only after value
Guests can inspect the useful result first, then create an account if they want to keep the chart.
Boundaries
BaZi results are reflective and educational, not medical, legal, financial, or safety-critical advice.
The system will not claim certainty about relationships, health, death, wealth, or irreversible decisions.
Paid reports must reference the exact chart facts that produced them.
Guest results should remain recoverable through the account save flow.
