Saju turns a birth year, month, day, and hour into four pairs of calendar signs. Here is what that structure means—and what it does not promise.
Year, month, day, and hour form one connected Saju chart. Learn what each pillar contributes and why none should be read alone.

Saju and BaZi share the Four Pillars and eight-character chart structure. The difference is best understood through language, history, and reading tradition—not a claim that they are unrelated systems.
