What Is Saju?
Saju means "four pillars" in Korean. It reads the moment you were born as eight characters and the balance of five elements between them.
Four pillars, eight characters
Your birth year, month, day and hour each become a pillar made of two characters: a heavenly stem on top and an earthly branch below. Four pillars times two characters gives the eight characters Korean readers call your chart.
The system is shared across East Asia and is known in English as the Four Pillars of Destiny (BaZi). Korea has its own reading traditions, vocabulary and conventions, such as how the hour around midnight is handled.
Why the exact time and place matter
Months in Saju start at solar terms, not on the 1st, and the year starts around 4 February. Being born a few minutes before or after a solar term can change your month pillar.
The hour pillar depends on local solar time. That is why we use your birthplace to correct for time zones, daylight saving and the position of the sun, instead of trusting the clock alone.
What a reading looks at
The day stem, called your Day Master, stands for you. Every other character is read in relation to it through the Ten Gods, and the whole chart is read through the Five Elements: wood, fire, earth, metal and water.
Ten-year luck cycles and yearly influences then show how the chart meets time, which is where questions about timing come from.
How to use it
Treat Saju as a vocabulary for patterns, not a script. It is for entertainment and self-reflection, and the most useful readings turn tendencies into questions you can act on.
Is Saju the same as Chinese astrology?
It shares its roots with the Four Pillars of Destiny (BaZi) but follows Korean reading traditions and terminology. It is not the same as reading only your year animal.
Do I need my birth time?
It helps. Without it you still get three pillars (year, month and day), and your Day Master is still known.
Can Saju predict the future?
No reading can promise outcomes. Saju describes tendencies and timing windows you can reflect on.
