What Is Saju?
Saju (사주, 四柱) means “four pillars.” It is the Korean system for reading a person from the exact moment they were born — and it is the foundation everything else on this site is built on.
The four pillars
Your birth year, month, day and hour each become a pillar. Every pillar holds two characters: a Heavenly Stem above and an Earthly Branch below. Four pillars, two characters each, eight characters in total — palja.
The Earthly Branches are the twelve animals most people already know. The Heavenly Stems are the five elements, each in a yang and a yin form. Together they cycle through sixty combinations, and that sixty-term cycle is what the Korean calendar has been counting for centuries.
Your Day Master
One character out of the eight stands for you: the Heavenly Stem of your day pillar, called the Day Master. Everything else in the chart is read in relation to it — what supports it, what drains it, what controls it.
This is why two people born in the same year can read so differently. The year is shared. The Day Master is not.
Balance, not prediction
A saju chart is read for balance. If your chart runs hot with Fire and thin on Water, a reading will say so, and it will say what that tends to look like in a life — quick to commit, slow to rest.
Saju does not claim to fix events in advance. It describes tendencies and timing. The useful question it answers is not “what will happen” but “what am I working with, and when does it get easier.”
How saju is used in Korea
Saju is ordinary in Korea in a way it is not elsewhere. People consult it before a marriage, before signing a lease, before naming a child, and at the start of a new year. It sits closer to a second opinion than to a religion.
Readings traditionally happen in person with a reader who has spent years on the classics. Saju Oppa keeps the calculation faithful and puts the conversation in your language, at any hour.
FAQ
- How do you pronounce saju?
- Roughly “sah-joo.” It is written 사주 in Korean and 四柱 in Chinese characters, meaning four pillars.
- Is saju the same as palja?
- They point at the same chart. Saju counts the four pillars; palja counts the eight characters those pillars contain. Koreans often say sajupalja for both at once.
- Does saju use the lunar or solar calendar?
- The pillars follow the solar terms, not the lunar months. That is why a birthday in early February can fall in the previous saju year.
