The eight characters come first
The moment of birth becomes eight characters. Solar-term boundaries and true solar time are corrected before the four pillars are set. The colour on each character is its element.
Where the energy has gathered
Which element overflows and which is missing. In this chart Metal is 39% and Water 1%; the needed elements are Water and Wood.
The long flow, ten years at a time
The peak for wealth and the peak for love come at different times. The picture says it first.
An example curve. The real chart differs for every birth chart.
What one minute separates
Solar-term boundaries are judged to the minute — a spot you miss if you only look at the date.
Right here in the browser, free
No sign-up; the calculation ends on this screen. Birth dates never reach a server.
Free Bazi chart with reading
From a birth date: eight characters, Five Elements balance, strength and your type among the 60 day pillars.
Free Bazi calculator
Four Pillars corrected to the solar term and true solar time, ten-year cycles and this year in one table.
Free Bazi compatibility
Two charts read on five axes with a grade, and what seat each of you holds for the other.
What makes it different
There are many Bazi apps. These three things set this one apart.
Precise calculation
It does not stop at the eight characters. Hidden stems, ten gods, twelve life stages and the relations between characters are all traced the way the classical system lays them out.
Data, not guesswork
Elements, ten gods, strength and the needed element are all computed from the chart, and the sentences are written against those values. Scores come from the calculation, never from a hunch.
From reading to using
Pick a purpose — moving, opening, contract, exam, job — and it finds good days. Wedding dates are read from both charts.
What is free
Try it first, then decide.
| Free | Points | |
|---|---|---|
| Today’s flow | Overall score · six areas · today’s reading | — |
| My chart | Natal chart · elements · temperament pentagon | All four chapters |
| Compatibility | Register the other person · grade · five axes · the seat each holds | Detail by relationship · an ex is read as reunion flow |
| Ten-year cycle report | Ridge chart | Report per cycle |
| Good days | — | Six purposes for picking a day |
Points also come from watching ads and daily check-ins. No ads are placed inside a reading. A reading you have opened stays free to reopen.
Sentences like these
Nothing that fits everyone. Below are sentences the app actually wrote, rendered in English.
Tends to prefer deciding alone, and feels hemmed in when following a way someone else has set.
A day when the usual way wobbles
Things do not go the way they usually do, and plans or seats already fixed are likely to be moved from outside.
A chart where the four areas flow at a similar level. Rather than one side jumping out, it carries on evenly.
Scores and grades are set by the calculation; the sentences only spell them out. The same chart gets the same judgement whenever you look.
Frequently asked questions
What if I don’t know my birth time?
Three pillars are calculated. If you learn the time later, correct it and look again.
Is this traditional Bazi?
It follows the classical Four Pillars system, in its Korean form called Saju, and states which line it takes where schools differ.
Does compatibility need the other person’s consent?
With their birth date you can register them under a nickname and look. Registering is free.
