Saju (四柱, “four pillars”) is the Korean name for the Four Pillars of Destiny, also known as BaZi in Chinese. Your birth year, month, day and hour are each written as a pillar made of one Heavenly Stem and one Earthly Branch, giving eight characters in total. Read with the classical Ziping method, they describe your temperament, aptitudes and the flow of your fortune.

How can I read my own saju?

Enter your date and time of birth on SAJUBY (sajuby.com) and we set up your Four Pillars chart with the classical Ziping method. You can then receive a report on your Day Master, Yongshin, and the flow of your 10-year luck cycles and whole life.

How is saju different from a daily horoscope?

A horoscope or fortune looks at short-term flows — today, this month, this year. Saju (Myeongri) analyzes the eight characters you were born with to describe your personality, aptitudes and the large 10-year cycles of your life. SAJUBY offers in-depth readings based on classical Myeongri.

Yongshin (用神, the “useful element”) is the one of the five elements — Wood, Fire, Earth, Metal and Water — that your chart needs most. It is chosen by weighing the strength of your Day Master, the season of your birth and the balance of the elements. Using the colors, directions and kinds of work that match it can help you make better use of your luck.

What is Daewoon (major luck cycle)?

Daewoon (大運) is the large flow of fortune that changes every 10 years. The element and Ten God each cycle brings into your natal chart set the general direction of that decade for money, work, relationships and health.

Gapja Day Pillar (甲子) — Personality, Career, Love & Wealth

The Gapja (甲子) day pillar pairs the day stem 甲 — The Great Tree — with the day branch 子 (Rat).

The Day Stem

Jia-mu is the great pillar tree — straight, firm, growing skyward without wavering. A natural leadership energy is built into the stem itself.

Decisive, persistent, and value-driven — easily trusted, suited to large-frame work in planning, founding, education, publishing.

Where It Sits — the Day Branch

Zi water is the still water of midnight in deep winter — outwardly quiet, inwardly the point where the new cycle begins. Quick-witted, perceptive, moving quietly.

With Zi in the day branch you think deeply and reveal little; others may find you hard to read. In the spouse palace it draws bright, practical partners — provided you both practise saying things aloud.

Twelve Life Stages

Bathing — exposed and shaken.

Challenges

Strong conviction can become rigidity. Hearing dissenting voices and pivoting are lifelong practices.

Environments & Relationships

East and spring; green tones; spaces with trees, books, paper. Thrives in environments where growth is visible.

Most stable when supported by mentors (in-seong) and steady earned partners (jeong-jae) in balance.
