Korean Saju 사주

사주팔자 saju palja: four pillars and the eight characters they carry.

Saju 사주 means four pillars. The chart is the same eight characters BaZi computes; the tradition reading them is Korean.

What it is

Saju reads the year, month, day and hour of a birth as four pillars of two characters. The calculation is shared with BaZi, so the eight characters do not differ between the two.

What differs is the tradition. Your day master is the ilgan 일간, the ten relationships are the sipseong, your decade cycles are daeun 대운, and a Korean reading is more willing to name the sinsal. Saju in Korea is also checked before decisions rather than consulted for entertainment, and that practicality shapes how a reading is written.

The ilgan and the daeun

Your ilgan 일간 is the day stem, the character that stands for you. Your daeun 대운 are the decade cycles, which say which stretches favour expansion and which favour consolidation. Both are read off the same ten stems the BaZi reference sets describe.

Method and sources

Charts are computed with deterministic libraries, corrected for true solar time at the birth longitude, and interpreted against the classical texts listed below.

Read against the same Ziping canon Korean practice reads, under Korean conventions:

  • 滴天髓 Ditian Sui Drops of Heavenly Marrow
  • 子平真詮 Ziping Zhenquan The True Interpretation of Ziping
  • 三命通會 Sanming Tonghui A Comprehensive Treatise on the Three Fates
