A 5-minute primer on Korea's Four Pillars system
Saju (四柱) literally means "four pillars" — the Korean name for the East Asian Bazi (八字) system. It reads a person using the year, month, day, and hour of birth, each represented by one Heavenly Stem (天干) and one Earthly Branch (地支). That's eight characters in total, forming a kind of cosmic fingerprint.
Unlike Western astrology, which maps planetary positions, Saju maps the energetic balance of the moment you were born — the relative strengths of the Wu Xing (五行, Five Phases): Wood, Fire, Earth, Metal, Water. From this balance, your Day Master (日干, the stem of your day pillar) is interpreted as "you," and the rest of the chart describes how the world meets you.
SAJU calculates this with the same precision used by traditional Korean masters — Lichun (Spring Begins) year correction, solar-term month boundaries, hidden stems with proper weighting (0.7 / 0.3 / 0.1) — and pairs it with an AI conversation that's grounded in your chart, not a generic horoscope.
