What is Saju?
A grounded introduction to Korean Saju: the four pillars of birth, eight characters, Five Elements, and what a reading can and cannot tell you.
Read the guideThe K Saju Decode guide
Saju starts with a birth date and, when known, a birth time. Those details are expressed as four pairs of traditional calendar signs. This guide explains the vocabulary before asking you to draw conclusions from it.
A Saju chart is a way to organize a traditional interpretation of tendencies and timing. It is not a scientific test of personality or a promise about future events. You can use it as a structured prompt for reflection, while keeping real decisions in your own hands.
