Saju Basics
Learn the Four Pillars system, one concept at a time
Six short guides covering what Saju actually is, how it compares to BaZi, your Day Master, the Four Pillars, the Ten Gods, and why exact birth time and place change your chart.
What Is Saju?
Saju (사주, 四柱) is Korea's traditional birth chart reading system. Learn what it means, where it comes from, how a reading actually works, and why it shows up in K-dramas.
Saju vs BaZi: What's the Difference?
Saju and BaZi both read the same eight-character birth chart from the classical Four Pillars of Destiny tradition. Here's how Korea's lineage differs from the wider Chinese-speaking tradition.
What Is a Day Master?
Your Day Master (일간) is the character in your Saju chart that represents you. Learn what it means and read a one-paragraph guide to all 10 possible Day Masters.
The Four Pillars of Destiny, Explained
The Four Pillars of Destiny (사주, 四柱) break your birth chart into Year, Month, Day, and Hour — eight characters in total. Here's what each pillar actually means.
The Ten Gods: A Complete Guide
The Ten Gods (십신, 十神) describe how every character in your Saju chart relates to your Day Master. Here's what all ten mean — money, power, expression, and support.
Why Birth Time Accuracy Matters
Birth time and birth city change your Saju chart more than most calculators admit. Here's why true solar time, historical time zones, and daylight saving all matter.
Reading about the concepts is one thing — seeing how they show up in your own chart is another.
