About Saju

What is Saju?

Saju (sa-ju), written 四柱, means “four pillars.” The year, month, day and hour of birth (yeon, wol, il, si) each become a pair of characters in this Korean tradition, which shares its roots with Chinese BaZi.

Each character belongs to one of five elements — Wood, Fire, Earth, Metal and Water (o-haeng). Pillar uses them to explore familiar experiences, personal tendencies and the flow of the year through traditional Saju interpretations. They do not guarantee future events.
