sajubti is a free service that combines the Day Master of Saju (the Korean Four Pillars of Destiny) with MBTI to describe your personality and your love, money and career tendencies through 160 characters.
In Saju, the Heavenly Stem of the day you were born, the Day Master, represents yourself. Each Day Master belongs to one of the five elements (Wood, Fire, Earth, Metal, Water) and is either Yang or Yin.
| Element | Read together with |
|---|---|
| Wood 木 | N (Intuition) |
| Fire 火 | E, F (Extraversion, Feeling) |
| Earth 土 | S, J (Sensing, Judging) |
| Metal 金 | T, J (Thinking, Judging) |
| Water 水 | I, N (Introversion, Intuition) |
Yang Day Masters (甲, 丙, 戊, 庚, 壬) lean towards E, and Yin Day Masters (乙, 丁, 己, 辛, 癸) lean towards I.
This mapping is an interpretive framework for reading the two systems together. It is not a scientifically proven model.
How are the 160 characters decided?
Your Day Master is the Heavenly Stem of your birth day, one of 10 (甲, 乙, 丙, 丁, 戊, 己, 庚, 辛, 壬, 癸). It is multiplied by your MBTI type (16 types), giving 160 combinations. The Day Master is calculated with a solar-term based calendar.
Is it free? Do I need an account?
Checking your character and the basic analysis are free and need no account. Saving compatibility records in the Korean version requires login.
Which languages are supported?
Korean (sajubti.art2meta.com) and Japanese (sajubti.art2meta.com/ja). There is no English version of the service yet.
What happens to my birth date?
No name or contact details are needed. The raw birth date is never sent to the AI; only the pre-calculated Four Pillars (stems and branches), an age band and your MBTI are used. See the Privacy Policy.
