What Is Saju? Korean Four Pillars of Destiny Explained
1 min read
Direct answer
Saju organizes birth into four pillars — year, month, day, and hour — and interprets patterns through the Day Master, Five Elements, and Ten Gods.
Key concepts
Saju reads the year, month, day, and hour of birth as four pillars, encoded with Heavenly Stems and Earthly Branches.
- Day Master — the Heavenly Stem of the day pillar, the chart’s reference point.
- Five Elements — Wood, Fire, Earth, Metal, and Water as a balance, not a label.
- Ten Gods — relational roles between the Day Master and the other stems.
How a chart is made
The same birth data always produces the same four pillars. Interpretation explains that chart; it does not change the calculation.

FAQ
What is Saju?
Saju (Four Pillars of Destiny) interprets personality, relationships, and life patterns from the year, month, day, and hour of birth.
How is Saju different from Western astrology?
Western astrology uses planetary positions against the zodiac. Saju uses the sexagenary cycle of Heavenly Stems and Earthly Branches. Both use birth time, with different frameworks.
Do I need an exact birth time?
Exact time completes the hour pillar. Without it, year, month, and day pillars can still be read.
Is Saju the same as BaZi?
They share the Four Pillars math. Saju is the Korean tradition and BaZi is the Chinese tradition. Emphasis and cultural context differ.
