What is Saju? Korean Four Pillars, explained.
Ancient precision. Your move.
Not fate, but a baseline: 사주팔자 saju palja maps your birth year, month, day, and hour into a chart of what runs strong, what drains you, and what to practice.
Day Masters
The ten day masters.
Your day master (일간 ilgan) is the character your entire chart is read around — ten types, five elements, each in a yang and a yin expression.
Your Eight Characters
A Saju chart starts as four pairs.
Each pillar has a heavenly stem above an earthly branch.

甲Yang Wood갑목
壬Yang Water임수

Together, the four pairs become the eight characters your reading is built from — the same chart your free card renders.
The highlighted character is the day stem — 甲 The Oak, Yang Wood. That is this chart’s day master: the character the other seven are read against.
The Four Pillars
Four moments of birth. Four layers of you.
Each pillar is one coordinate of your birth — and each one reads a different layer of how you operate. Together they hold the eight characters your entire chart is built from.
日Day · 일
Self
Temperament, appetite, stress, and leverage.

Season
Upbringing and the strongest seasonal signal.

Era
Public climate and inherited patterns.
Charts follow the traditional layout: hour pillar on the left, year pillar on the right — reading from your innermost layer outward.
Five Elements
Five elements. Two cycles.
In 명리 myeongli, the elements are not isolated traits. Wood, Fire, Earth, Metal, and Water feed, drain, control, and correct each other.
- Generating
- Growth, support, and restored momentum.
- Controlling
- Friction, discipline, and pressure.
A chart becomes personal when you see which relationships are doing the work.
Common Questions
Q.Is Saju the same as astrology?
No. Astrology reads planetary positions; Saju reads the East Asian calendar of elements and stems. Different lineage — Korean myeongli (명리), not the zodiac.
Q.Is Saju the same as Bazi?
Same Four Pillars root (八字). Bazi is the Chinese lineage; Saju is the Korean one, with its own interpretive conventions.
Q.Do I need my exact birth time?
No. Year, month, and day still give you your day master and elemental balance. The hour pillar adds timing detail — add it anytime.
Q.Is Saju fortune telling?
No. Saju Lore maps patterns — what runs strong, what drains you, what to practice — as software-generated reports for self-reflection and entertainment.
