Dagil SajuFrom input to result
We take your birth date, time and place
The longitude of the birthplace sets true solar time; that year's solar terms set the month boundaries. Daylight saving and past standard-time changes follow tzdata as it is.
We calculate the saju
We build the four pillars from stems and branches, then read the ten gods, the useful god, the shinsal, and the ten-year luck cycles.
We calculate the Zi Wei chart
We fix the life palace, place the major stars across the twelve palaces, then read the four transformations and the ten-year limits.
Only the overlap becomes a verdict
The grade is the two calculations added together. What only one side says is not raised to a verdict — it drops to 'for reference'.
What we don't say
- We don't invent counts, probabilities or time windows the calculation doesn't produce. A line like '70% within three months' comes from nowhere in the math.
- We don't rule on another person's character, on illness, on a court outcome, or on an amount of money.
- We don't write fake reviews or fake user numbers.
The numbers on screen are counted ones only, like how many cards and videos were actually made today.
What the AI does
The calculation and the grade come from a rule engine (code). AI (Gemini) is used in two places only.
- Translation — moving sentences written in Korean into the other languages.
- The Dagil counselor — it reads the finished calculation and answers from it. It does not change the calculation.
The AI does not produce a grade or a date.
Schools and sources
The frameworks the calculation follows.
- Ziping saju — the ten gods, the useful god (strength balance and climate)
- Zi Wei Dou Shu, San He school — the 14 major stars, the four transformations
- Solar terms — from astronomical calculation
Reference works: Ziping Zhenquan · Ditian Sui · Qiongtong Baojian · Zi Wei Dou Shu Quanshu
Limits
- If the birth time is unknown we calculate without the hour pillar, and precision drops accordingly.
- Two people with the same chart still live different lives.
- The decision is yours.
