What is Saju (Korean Four Pillars)?
Saju (사주), or the Four Pillars of Destiny, is Korea’s traditional reading of the two characters — a Heavenly Stem and an Earthly Branch — for the year, month, day, and hour you were born. Together they form eight characters (사주팔자) computed from the Manseryeok (만세력) calendar. Your Day Master (the day’s stem) is the “you,” and the balance of the five elements — Wood, Fire, Earth, Metal, Water — shapes your temperament, relationships, and timing. It’s the Korean cousin of Chinese BaZi and, in spirit, of the Indian kundli birth chart.
Saju calculator — FAQ
Do I need my exact birth time?
Not to start. Your year, month, and day pillars — and your day master and Korean zodiac — don’t need a time. Birth time only sets the hour pillar, so add it for a fully exact chart.
Is this the same as Chinese BaZi or an Indian kundli?
It’s the Korean tradition (Saju / Four Pillars). It shares roots with Chinese BaZi and, like a kundli, reads your birth chart — but the method, the day-master focus, and the Korean interpretation are their own.
