What the calculator gives you

🏛️

Your Four Pillars chart

All eight characters (사주팔자) — the Heavenly Stems and Earthly Branches of your birth year, month, day, and hour, calculated with the traditional solar-term calendar.

☀️

Your Day Master

The character at the center of your chart — which of the 10 Day Masters you are, and the personality signature that comes with it.

🌊

Five-element balance

How Wood, Fire, Earth, Metal, and Water are distributed across your chart — what you have in excess and what you run low on.

📈

Luck cycles & this year

Your 10-year luck cycle (대운) timeline with your current chapter marked, plus what the current year activates in your chart.

02

The engine calculates your chart

A purpose-built saju engine converts your birth moment into the eight characters using the solar-term calendar — the same method a Korean practitioner uses.

Read your interpretation in English

Your chart, Day Master personality, and element balance are interpreted in natural English — free.

Saju calculator FAQ

Yes. Your Four Pillars chart, Day Master reading, five-element balance, and luck-cycle timeline are completely free, with no sign-up required. A one-time premium upgrade ($2.99) unlocks ten deeper AI-written sections — love, money, career, timing, and more. No subscription, ever.

No. The calculator accepts an unknown birth time and still builds your Year, Month, and Day pillars — about 75–80% of the full chart, including your Day Master and element balance. If you later learn your birth hour, you can add it for the complete picture.

Essentially yes. Saju (사주) is the Korean tradition and bazi (八字) is the Chinese one — the Four Pillars calculation is the same. This calculator follows the Korean saju convention, with results explained in English.

The chart math is deterministic — your eight characters are computed from the traditional solar-term (절기) calendar, not approximated from Western zodiac dates. Two practitioners would derive the same chart; interpretation is where traditions vary, and ours follows mainstream Korean saju.

Yes — you can add charts for partners, friends, or family, and compare any two charts with the compatibility (궁합) reading.
