Curious? Fair.
What is Saju?
Saju (사주) is Korea's Four Pillars system, studied for over a thousand years. Your birth year, month, day, and hour each form a "pillar" of two characters — eight in total — describing your elemental blueprint: the mix of Wood, Fire, Earth, Metal, and Water you were born with. It's long been used as a lens for self-understanding and reflection.
How is it different from a personality quiz?
A quiz asks you to describe yourself. Saju reads the five elements — Wood, Fire, Earth, Metal, Water — computed from your exact birth time down to the two-hour window. It's read here as a portrait for reflection: the tendencies you were born with and the seasons your chart leans through, not fixed outcomes.
Why do you need my birth time and city?
The hour sets your fourth pillar, and the city sets the timezone your pillars are computed in — a birth in Los Angeles and one in Seoul at the "same time" have different charts. We compute this precisely, including historical daylight-saving rules. No time? We read three pillars and tell you what changes.
Is the calculation accurate?
The chart math is deterministic — the same rules a Korean manseryeok (traditional almanac) uses, cross-checked against independent sources. That's also why we don't let a chatbot guess your chart: AI writes the reading, but the pillars come from verified calculation.
