- 1Open the assistantIt is a public GPT — no key, no signup with us.
- 2Give it your birth detailsDate, time (or the two-hour 时辰) and the city you were born in. Birthplace matters: the chart is corrected to true solar time, which depends on longitude.
- 3Read the chart it castsMain star and its rarity, all twelve palaces, the Four Pillars, your Day Master and the five-element balance.
Where the readings come from
The chart itself is calculated, not generated — the same deterministic engine, from the same birth data, returns the same chart every time. The interpretations this site publishes are rule-based on 15 classical texts rather than written fresh by a language model; the full bibliography is public.
See the source list at /sources, or the calculation endpoint the assistant calls at /api-docs.
What it will not do
- · It returns calculated chart structure and explains traditional terms. It should not invent personal predictions or interpretation chapters beyond the information returned by the calculator.
- · Follow the returned chart link to explore your free chart. Sign in on the site to save it and read your personal preview.
- · Our calculation endpoint does not write submitted birth details to our database. Your ChatGPT conversation is governed separately by your ChatGPT settings and OpenAI’s policies.
- · Zi Wei Dou Shu and BaZi are traditional symbolic systems offered for reflection, not verified prediction.
