Korean Four Pillars calculator
Your birth moment written as eight characters: four pillars, each one a pair. In Korea this lookup is free everywhere and every reading starts from it. Free here too — no signup, and nothing is stored.
Without a time you still get three of the four pillars — including the day pillar, which is you.
Free, instant, and nothing is saved.
What the four pillars are
Saju means “four pillars”. One pillar comes from the year you were born, one from the month, one from the day and one from the hour. Each pillar has a top character (a heavenly stem) and a bottom character (an earthly branch, the one people know as an animal sign). Four pairs, eight characters — which is why Saju is also called Paljja, “eight characters”.
Why the day pillar is you
Western astrology reads the month of birth. Saju reads the day, and the top character of the day pillar is called the Day Master — the one that stands for the person. Everything else in the chart is described by how it meets that character: what feeds it, what drains it, what it controls, what controls it.
If you don’t know your birth time
You still have a chart. The hour pillar is left empty rather than guessed, and the other three — including the day pillar that stands for you — are exact. Most of what a reading says comes from those. Adding the hour later adds detail; it does not replace the rest.
The five elements, and what a gap means
Every character belongs to one of five elements: wood, fire, earth, metal, water. The balance above is weighted rather than counted — characters hidden inside each branch and the season of the month pillar carry weight too. An element that never appears is not a fault. It is usually the part of a life that has to be built on purpose, and it is one of the first things a reading talks about.
