Saju Analysis is a free web service that lets anyone analyze their Four Pillars chart in depth, grounded in the classical principles of Ming Li astrology. We combined an accurate calculation engine with rich interpretation so that even readers new to the tradition can approach it comfortably.
Our goal
The wisdom of Saju (Four Pillars) astrology has accumulated for over a millennium across East Asia. Yet because of its Chinese terminology and intricate structure, many people only encounter fragmentary readings without truly understanding their own charts.
This service is built on accurate calendrical calculation and brings together the core elements of Ming Li analysis: the four pillars, the five elements, the Ten Gods, the Useful God, the twelve life stages, sinsal, geokguk, hap-chung-hyung-pa-hae, hidden stems, voids, Najib elements, and the Daeun / Seun / Wolun cycles.
No registration is required — enter your birth information and see the analysis instantly. The interface is fully responsive for mobile use.

Our stance on Ming Li astrology
Saju is not a tool for predicting fate but a mirror for self-understanding. By learning your strengths, weaknesses, fortunate phases, and times that demand caution, you can make wiser decisions in life.
The results offered here are reference information based on traditional theory and must not be used as the basis for medical, legal, or financial decisions. Life is ultimately shaped by your own choices and effort.
