In short: the chart is computed (deterministic calendar math). The reading is a rule-based plain-language translation — not a prediction. We don't promise outcomes; we give you a way to check the framework against your own past.
Computed, not predicted
🎉 Free during beta: our payment channel is under review, so all membership features are currently free — full reading, unlimited past-event validation, follow-up tracking, and per-month deep dives. No payment required. Leave your email below and we'll notify you (with a beta-user discount) when billing opens.
What it does
- BaZi (Four Pillars) — year / month / day / hour pillars, Ten Gods (十神)
- Zi Wei Dou Shu — the twelve palaces, life palace, current major decade (大限)
- Yearly & monthly flow — 12-month table plus an energy curve you can export as PNG
- Past-event validation — enter real life events (marriage, moving, job changes) and see whether the chart's flow harmonises with them
- Follow-up tracking — dated, checkable statements you later mark as met / partly met / not met, so you build your own hit-rate
What makes it different
Most sites hand you an AI-written reading and ask you to trust it. We do something less exciting but more honest: we publish the rules, and we let your own timeline decide whether the framework explains anything.
- Deterministic charting — same birth data + same rules = same chart, every time, recomputable
- Rule-based reading — translations come from explicit rules (Ten Gods, palace logic, yearly activation), not improvised mysticism
- No fear-selling — no "pay to fix your fate", no doom predictions, no life-or-death claims
- Local-only data — your birth information stays in your browser's local storage; we don't upload it
Rules we use (short version)
| Item | Our choice |
|---|---|
| Month boundary | By solar terms (定气法), not by the lunar month |
| Year boundary | By Lichun (立春, start of spring) — applied to both BaZi and Zi Wei |
| Late-Zi hour | Born 23:00–24:00 → the day pillar rolls to the next day |
| Zi Wei engine | Built on the open-source iztro library, default star-placement |
| Energy curve | A deterministic rhythm score from the month's Ten God plus branch relations — for pacing output vs. consolidation, not a luck forecast |
| Not implemented yet | True solar time (no longitude/time-equation correction); unknown birth hour not supported |

Honest notes
- The chart tool's interface is Chinese-first. These English pages document the method; a fully English UI is on our roadmap. If that's a dealbreaker today, we'd rather say so than waste your time.
- We don't claim scientific validity. We treat this as a traditional cultural framework you can evaluate for yourself — that's the whole point of the validation mechanism.
- Not advice. Nothing here is medical, financial, legal or life-decision advice.
