What Is Saju? A Beginner's Guide to Korean Four Pillars Astrology
Saju (사주), literally "four pillars," is a traditional Korean system for reading personality and life tendencies from the moment someone was born. It's built on the same underlying framework as Chinese Bazi (八字) astrology, using the year, month, day, and hour of birth to build a chart of four "pillars," each made up of a Heavenly Stem and an Earthly Branch.
Those eight characters (four stems, four branches) map onto the Five Elements — Wood, Fire, Earth, Metal, and Water — giving a picture of a person's elemental balance. The single most important character in the chart is the Day Master: the Heavenly Stem of the day pillar, traditionally treated as the core of a person's identity.
Saju is widely practiced in Korea today, often in a light, casual way — similar to how MBTI or Western astrology gets used in conversation. This site treats it the same way: for entertainment and self-reflection, not as a substitute for professional advice.
