SAJUGO brings authentic Korean Myeongri (Saju) to the world — powered by an astronomy-based manseryeok engine, in your language.
Online Saju content is everywhere, but few sites show their work. We compute solar terms and the Four Pillars directly from astronomical calculations, then have the results reviewed by real Saju masters. This is authentic Korean Saju — not Western astrology — and we want you to see exactly how each chart is calculated, not just take our word for it.
From your Four Pillars chart to compatibility, tarot, and naming — one birth date, many stories.
How is it calculated?
Your birth date and time are converted to solar terms and the sexagenary cycle through astronomical calculation, then cross-checked against verified almanac data.

Solar terms and day pillars are computed astronomically and cross-checked against authoritative almanacs.
Reproducible readings
The same birth date always yields the same result — deterministic, not random day to day.
Private by design
Sensitive data is encrypted with a per-user key and irrecoverably shredded on deletion.
Core readings — your chart, lifetime saju, and daily fortune — are free. The in-depth interpretation report and premium reports are paid.
Traditional Myeongri rules are implemented deterministically for reproducibility. This service is for entertainment and cultural reference.
Sensitive data such as your birth date is stored encrypted (AES-256-GCM) and safely destroyed on request.
