Korean Astrology: What Is Saju?
When people say "Korean astrology," they usually mean Saju — literally "four pillars." Unlike Western astrology, it does not use planets. It uses the traditional calendar: your birth year, month, day and hour each become a pillar made of two characters, eight characters in total.
The 10 Day Masters
The first character of your birth-day pillar is called your Day Master. It represents you. There are ten: Yang Wood, Yin Wood, Yang Fire, Yin Fire, Yang Earth, Yin Earth, Yang Metal, Yin Metal, Yang Water and Yin Water.
We scored all 51,840 charts for each Day Master with the same rules. The averages are close — the gap between the highest (Yang Water, 67.5) and the lowest (Yin Metal, 65.6) is only 1.9 points. In other words, no Day Master is simply "good" or "bad."
What changes the result most
Your birth hour. With the same birth date, changing only the hour moved the score by 18.7 points on average — about ten times the gap between Day Masters. That is why a Saju reading should always include the hour you were born.
