About BaZi Atlas

Other trust pages: Sources · Corrections · Chart rules · Disclaimer · Methodology

BaZi Atlas is an independently maintained reference for four-pillar bazi. Every number on the site is computed by one versioned engine; every convention is published with its basis and its limits; every public fix stays in the corrections log. The site launched on 2026-09-16 and is maintained by an independent developer based in Shenzhen, China — no company, no investors. The corrections log is the track record.

How the site is built

  1. Every number is computed. Pages are generated by factory code from a single engine; templates only lay out, never invent. That is the mechanism against AI content farming: a summary cannot produce a checkable fact such as which four stems never sit on their own Prosperity branch.
  2. Divergences are published, not hidden. Where the tradition itself splits (late zi hour, true solar time, two colour systems…), both readings are computed, both shown, with the gap stated. The wedding picker marks day by day whether the two colour systems agree — exactly 72 of 144 combinations do.
  3. Corrections are public. Every engine fix enters the corrections log with how it was verified and what was declared unchanged. Why the old number was wrong, how it was found, how it was confirmed — nothing is silently patched.
  4. Limits are declared. There is no astronomy in the browser: the four separated / four exhausted days are not in the wedding score; term instants come from an offline minute-level table, not runtime astronomy. Every page declares its known limits in a dedicated section.

Who maintains it — and what this site is not

The maintainer is an independent developer (Shenzhen, China); the site has run since 2026-09-16. There is no paywall, no advertising, no login system.

What this site deliberately does not do: assign fixed personalities to components (one character per branch, one destiny per star); make predictions; or give advice of any kind. See the methodology and disclaimer pages for why.

Frequently asked questions

Who built this site?
An independent developer based in Shenzhen, China. No company, no investors. The site launched on 2026-09-16, and every fix ever made is public in the corrections log.
Is the content AI-generated?
Pages are assembled by code from one engine, and the tables in that engine are cross-checked against independent sources before they are encoded. Every page carries the engine version, so any number you see can be re-checked. That is the line between this site and AI content farming.
Why should I trust the calculations?
Because they are checkable: every convention is published (R13–R38); calendar-level data is reconciled day by day against an open calendar library (day officers over 628 days, mansions and day spirits over 900 days, zero mismatch); the luck-pillar arithmetic has a 4,939-assertion regression suite; and fixes are never silent — they go to the corrections log.
How often is it updated?
In step with the engine version and the corrections log: every engine fix bumps the version and is recorded on the methodology page. The most recent public correction is dated 2026-09-16.

Reference index

Every enumerable component of ba zi has its own page here. Each page is computed by the same engine and can be checked item by item — none of it is a personality table.
