In our last post, we broke down the Four Pillars of your birth chart. You now know that your Saju is a map of your life’s timeline. But to read that map, you need a starting point—a “You” on the map.
That starting point is the Day Master.
What is the Day Master?
The Day Master is the character located at the top of the Day Pillar (the 3rd column from the right). In Saju terminology, this is called the Heavenly Stem of your birth day.
While your birth year (e.g., Year of the Dragon) gives you a general “vibe,” the Day Master represents your soul, your ego, and your essential nature. It is the “I” in the statement “I am.”
How to Find Your Day Master
- Open a Saju Calculator (Manse-ryeok).
- Enter your birth date and exact birth time.
- Look at the third column from the right (The Day Pillar).
- The top character in that column is your Day Master.
There are 10 possible Day Masters, based on the Five Elements (Wood, Fire, Earth, Metal, Water), each divided into Ying and Yang.
The 10 Faces of the Soul
Which one are you? Here is a brief look at the 10 types of Day Masters:

🌳 Wood (Growth & Kindness)
- Yang Wood (Jia): Like a towering pine tree. Straight, sturdy, and independent. You are a natural leader who hates being restricted.
- Yin Wood (Yi): Like a flexible flower or ivy. Resilient, diplomatic, and artistic. You know how to adapt and survive in any environment.
🔥 Fire (Passion & Expression)
- Yang Fire (Bing): Like the Sun. Radiant, generous, and honest. You light up every room but can be impulsive.
- Yin Fire (Ding): Like a candle or a lantern. Warm, meticulous, and spiritual. You shine brightest in focused, intimate settings.
⛰️ Earth (Stability & Trust)
- Yang Earth (Wu): Like a massive mountain. Reliable, stubborn, and protective. You are the rock people lean on.
- Yin Earth (Ji): Like fertile garden soil. Nurturing, productive, and multi-talented. You have a deep sense of internal discipline.
⚔️ Metal (Justice & Clarity)
- Yang Metal (Geng): Like a raw sword or axe. Tough, decisive, and loyal. You value justice and aren’t afraid of a challenge.
- Yin Metal (Xin): Like a polished diamond or jewelry. Elegant, sharp-witted, and sensitive. You have high standards and a unique brilliance.
🌊 Water (Wisdom & Flow)
- Yang Water (Ren): Like the vast ocean. Adventurous, intelligent, and powerful. You have a grand vision for life.
- Yin Water (Gui): Like a gentle spring or mist. Intuitive, sensitive, and mysterious. You see things others miss.
Why Does This Matter?
Knowing your Day Master is like knowing your blood type or your MBTI—but deeper. It tells you:
- Which environments make you thrive.
- How you react to stress.
- Who you are most compatible with.
Everything else in your Saju chart—your wealth, your career luck, and your relationships—is calculated based on how they interact with this Day Master.
