Saju (사주, 四柱) literally means "four pillars" — the four pairs of Heavenly Stems and Earthly Branches that correspond to your birth year, month, day, and hour. Together, they form a chart that Korean fortune tellers have read for centuries.
Each pillar contains two characters: a Heavenly Stem (天干) representing one of ten elements, and an Earthly Branch (地支) representing one of twelve zodiac animals. The interaction of these eight characters (팔자, 八字) reveals your elemental balance.
The five elements — Wood (木), Fire (火), Earth (土), Metal (金), and Water (水) — form the foundation of Saju interpretation. A balanced chart suggests harmony, while dominant or missing elements indicate strengths to leverage and challenges to navigate.
Your Day Master (일간) — the Heavenly Stem of your birth day — is considered the most important element, representing your core self. Understanding your Day Master reveals your personality, career tendencies, and relationship patterns.
