Korean life, beginning with Myeongli
When a child is born in Korea, parents consult Saju. They choose a name that aligns with the child's birth chart, reading the tendencies written in the moment of birth. When the child grows up and finds love, the families check gunghap — compatibility between two charts. Moving to a new home? They confirm a day free of ill influence. Opening a business? They select an auspicious date. As each new year begins, Koreans check their yearly fortune and prepare for a fresh start.
"Egu nae paljaya" — an exasperated sigh Koreans use when life throws a curveball, roughly: "Oh, this fate of mine!" — a phrase every Korean has uttered at least once. Surveys show that 84.5% of Korean adults have experienced Saju or fortune-telling at least once[2]Embrain Trend Monitor, January 2022 survey. 1,000 adults aged 19–59 nationwide in South Korea.. Saju has accompanied every chapter of life. From the name you receive at birth, through love and decisions, to the start of each new year — it has always been there.
Korea's orthodox Myeongli tradition, state-managed for centuries
A state bureau called Gwansanggam handled date selection, naming, and compatibility, while state examinations selected specialists.
Gwansanggam · State Bureau
Joseon established Gwansanggam (觀象監), a state bureau responsible for date selection, naming, and compatibility. For 500 years, the state directly managed this discipline's quality.
Gyeonggukdaejeon · State Exams
Joseon's national code, Gyeonggukdaejeon, formally codified the Eumyanggwa (陰陽科) examination. Specialists were selected and trained through state examinations.
Chiljeongsan · Independent Calendar
King Sejong compiled Chiljeongsan (七政算), an independent calendar system. It elevated the precision of seasonal and temporal calculations essential to Saju analysis.
Gwansanggam discussed Saju only upon precise calendrical data. The Hojakdo Engine carries on this principle.
Hongik Ingan (弘益人間) — 'Benefit all humanity.' This founding ideal, honoring the bond between heaven and humanity, is commemorated every October 3rd on Gaecheonjeol (開天節) and endures as Korea's guiding educational philosophy.
