Korean Astrology is Saju, Korea’s Four Pillars tradition
Saju (사주, 四柱) turns the year, month, day, and hour of birth into four pillars. English speakers commonly encounter it as Korean Astrology, Four Pillars, or BaZi.

Five Elements and Day Master
The chart is read through Wood, Fire, Earth, Metal, and Water together with the Day Master, the stem of the day pillar. SajuMira explains these in plain language on the user-facing screens.
Different from Western astrology
Saju calculates pillars from calendar and solar-term rules, while Western astrology calculates planets and angles at the birth moment. SajuMira keeps the two systems separate before comparing them.
Korean and English
The same service can be read in Korean or English. English pages use both Saju and Korean Astrology terminology so first-time readers can connect the Korean name with the broader search term.
How SajuMira reads Korean Astrology
We calculate Saju first and a Western natal chart separately. The reading then shows where the two traditions point in the same direction and where they do not.
