Free Four Pillars (Saju) Chart

What is Sajugazer?

Sajugazer is a browser-based Saju (四柱) analysis platform that reads the cosmic energy encoded in your birth time. Saju, known as the Four Pillars of Destiny, is one of the oldest systems of self-understanding in Eastern philosophy. It uses the year, month, day, and hour of your birth to generate eight characters — four Heavenly Stems and four Earthly Branches — that form a unique energetic blueprint of your personality, relationships, career potential, and life timing.

Our engine computes your Four Pillars chart using astronomical algorithms, then interprets it through the traditional frameworks of Ten Stars (Sipseong), Fateful Stars (Sinsal), 12 Stages of Energy (Unseong), and Five Element balance. All computation runs entirely in your browser — no birth data is transmitted to any server.

How It Works

Step 1: Go to the chart calculator and enter your birth year, month, day, hour, minute, gender, and birth region.

Step 2: Click "View Results!" to generate your Saju chart. You will see your Four Pillars, Ten Stars, element proportions, and Decade Analysis timeline.

Step 3: Use the analysis tools to get detailed readings — from a comprehensive Total Analysis covering personality, love, and wealth, to time-specific Daily, Monthly, Yearly, and Decade analysis readings.
