How it works
Calculated first. Written second.
Calculated in code
Your chart is computed by deterministic engines — solar terms to the minute, true solar time from your birthplace, the 立春 year boundary. Same input, same chart, every time.
Written with care
AI turns the computed chart into plain language. It is checked against the chart, kept calm and kind, and never allowed to add, remove or change a single pillar or star.

How these systems actually work
What is BaZi? The Four Pillars, explained
BaZi (八字, Four Pillars) writes a birth moment as eight characters of the Chinese calendar: how the pillars are found and what tradition reads in them.
The I Ching three-coin method: 6, 7, 8 and 9 explained
How three coins build an I Ching hexagram: coin values, the numbers 6 to 9, moving lines, the changed hexagram and the order to read it all in.
Why your zodiac animal begins at the Start of Spring (立春)
In the Four Pillars tradition your zodiac animal changes at the Start of Spring (立春), not at Lunar New Year. Edge cases, the 60-year cycle and 2027.
Questions
All questions →Is this a prediction of my future?
No. TianEon presents traditional Chinese systems as a way to reflect, not to predict.
How are the charts calculated?
Entirely in code, before any AI is involved. Solar terms come from astronomical tables to the minute; the year changes at the Start of Spring (立春); the day and hour pillars use true solar time from your birthplace's longitude. Zi Wei Dou Shu is computed with the open-source iztro library. The same input always gives the same chart, and the calculation notes are shown on every result.
What does the AI do — and what doesn't it do?
It only writes the words. The AI receives the already-calculated chart as data and turns it into plain language. Every reading is checked against the chart: it may not add, remove or change a pillar, star or line, and it is kept calm — no fear, no health or lifespan claims. If a draft fails those checks it is rewritten or replaced by a template.
I don't know my birth time. Can I still use it?
For BaZi, yes: you'll get three pillars (year, month and day) and the hour pillar is left out; some details, like strength, become less certain and we say so. Zi Wei Dou Shu needs the hour, so it asks for one. The zodiac calculator only needs the date.
Why is my zodiac animal different from what I've read elsewhere?
Most calendars change animal on 1 January or at Chinese New Year. The Four Pillars tradition changes it at the Start of Spring (立春), around 4 February, to the minute. If you were born between late January and mid-February, your animal can differ — the calculator shows both.
