About Saju
Saju (사주, Four Pillars) is the Korean tradition of destiny reading, sharing the same Chinese-origin four pillars system but developing unique cultural emphases. Korean Saju places special importance on Sinsal (신살, Symbolic Stars) such as Dohwasal (도화살, Peach Blossom Star for charm and romance), Yeokmasal (역마살, Travel Horse for mobility), and Hwagaesal (화개살, Canopy for artistry and spirituality). The Ilgan (일간, Day Master) represents your core personality, while Sipsung (십성, Ten Gods) map to career, wealth, relationships, and talent.
How to read your Saju (사주) chart
Saju is the Korean tradition of Four Pillars destiny reading. Here's how to interpret yours in three steps.
Enter your birth details
Provide your birth date, time, and gender. Saju uses the same Four Pillars framework as Chinese Bazi, with Korean interpretive emphasis.
Find your Il-gan (Day Master)
Your Il-gan — the heavenly stem of your day pillar — is your core self in Korean Saju. It reveals your fundamental nature.
Check your Daewoon (luck cycles)
Your current Daewoon (10-year cycle) shows the dominant energy of this phase of life.
The Korean Saju tradition
Saju (四柱, "four pillars") is deeply woven into Korean culture — consulted for weddings, career changes, and major decisions. It shares its roots with Chinese Bazi but has developed distinct Korean interpretive schools and terminology.
O-haeng: the five elements in Saju
Saju analyzes O-haeng (오행) — Metal, Wood, Water, Fire, Earth — to assess balance. Which element dominates your chart, and which is weak, reveals your tendencies and what you need to cultivate.
Sin-sal: special stars in your chart
Korean Saju places emphasis on Sin-sal (신살) — symbolic stars that mark talents, challenges, or turning points. Stars like the flower star (Taehwa) or travel star (Yukma) add color to the reading.
Frequently Asked Questions
What is Saju (사주)?
Saju is the Korean practice of Four Pillars destiny reading. It uses your birth year, month, day, and hour to construct a chart of Heavenly Stems and Earthly Branches, interpreted through Korean cultural and philosophical traditions.
How is Korean Saju different from Chinese Bazi?
Both share the same four pillars calculation engine. The difference is in interpretation emphasis: Korean Saju places much greater weight on Sinsal (신살, Symbolic Stars) and uses Korean terminology (Ilgan, Sipsung, Daewon) to frame readings.
What are Sinsal (신살)?
Sinsal are symbolic stars calculated from your chart's branches. They indicate specific influences — Dohwasal for charm and popularity, Yeokmasal for travel and change, Hwagaesal for artistic talent and solitude.
Can Saju predict my future?
Saju maps your elemental composition and timing cycles to identify favorable and challenging periods, not fixed events. Korean practitioners read the Daewon (decade cycles) and yearly fortune as weather patterns for decision-making. Saju is treated as guidance for self-understanding and timing, not deterministic fortune-telling.
What is Ilgan (일간) in Saju?
Ilgan, the Day Master, is the Heavenly Stem of your day pillar. It represents your core self and is the reference point for the entire chart. A Yang Wood Ilgan (갑/甲) expresses growth and benevolence, while a Yin Water Ilgan (계/癸) is adaptive and intuitive. All other stems and branches are read in relation to it.
What is Daeun (대운) in Korean Saju?
Daeun are decade fortune cycles that show which elements influence each ten-year period of your life. They begin at different ages depending on your gender and year stem polarity. A favorable Daeun brings supporting elements; an unfavorable one may introduce conflict. Practitioners read Daeun alongside your natal chart for timing guidance.
