How to Read a Korean Saju (Four Pillars) Birth Chart

A Korean Saju (사주, Four Pillars of Destiny) reading turns your birth date and time into four pillars — year, month, day, and hour — each a pair of a Heavenly Stem and an Earthly Branch. Here is how to actually read one, and a free tool that computes it for you.

The four pillars

Pillar What it represents
Year Ancestry, early environment, the broad era you were born into
Month Career, social self, parents
Day You — the Day Master is the anchor of the whole chart
Hour Children, later life, inner drive

Reading order that actually works

  1. Find the Day Master (the day pillar's stem) — this is you.
  2. Weigh its strength against the season (the month branch) and the other pillars.
  3. Find the useful god — the element that balances a too-strong or too-weak Day Master.
  4. Only then read wealth, career, and relationship signals relative to the Day Master.

Why the date math matters

Month pillars switch on solar terms (절기), not calendar months, and the hour pillar depends on true local solar time. A reading built on the wrong term boundary is wrong from pillar two onward.

You can generate your own chart — pillars, Day Master, and elements — for free, in the browser, no sign-up:
