Korean Saju · Four Pillars of Destiny

Your birth chart,
calculated by the stars.

In Korea, people visit a saju reader before big decisions. Scholars read destiny from the exact position of the sun when you were born. We do the same math, to the minute, for the city you were born in, and show you every step.

Why it's different

Most saju apps guess. We calculate.

A Four Pillars chart depends on the exact minute the sun crossed a solar term, and on the real sun time where you were born. Get either wrong and the whole chart changes. Many apps use calendar dates and clock time. We don't.

Precise

Month pillars change at the exact solar-term moment from an astronomical ephemeris, not on a fixed calendar date. Historical daylight-saving rules for your country are applied.

Transparent

Every chart shows its working: clock time → daylight saving → longitude → the equation of time → true solar time. Every sentence in your reading points to the part of your chart it comes from.

Personal

Tell us the one question on your mind. Your reading answers it, and ends with one concrete thing to do this month. No vague horoscope lines.

How we calculate

Four steps, every one shown to you

  1. Find your true solar time. We correct your clock time for daylight saving, for how far east or west you were born within your time zone, and for the equation of time (Earth's tilted, elliptical orbit).
  2. Place the solar terms. The 24 solar terms are computed with the Swiss Ephemeris, so your month pillar flips at the right minute.
  3. Build the four pillars. Year, month, day and hour, each a Heavenly Stem and an Earthly Branch, using the traditional sexagenary cycle.
  4. Read the balance. We count the Five Elements, find your Day Master, and map your 10-year luck cycles. Then we write your reading from that, and only that.

Checked against 500 randomly generated birth moments and published reference charts before launch.

Questions

Good to know

What is Saju?

Saju (사주, "four pillars") is the Korean form of the Four Pillars of Destiny. Your birth year, month, day and hour each become a pair of characters from the traditional sexagenary cycle. Readers interpret the balance of the Five Elements in those eight characters.

I don't know my birth time. Can I still use it?

Yes. We build three pillars (year, month, day) and tell you clearly which parts of the reading depend on the hour.

Why does my birth city matter?

Saju uses the sun's real position, not the clock. Two people born at 9:30 PM in New York and in Chicago have different true solar times, and sometimes different hour pillars.

Is this a prediction of the future?

No. Saju is a traditional framework for reflection. Readings are for entertainment and self-reflection, and are not medical, legal, financial or psychological advice.
