What exactly is a Day Pillar in Korean Fortune Telling Saju?
Hello everyone!
I’ve been steadily building the foundation of this blog by sharing stories about Korean saju and Four Pillars astrology as they appear in our daily lives. We’ve covered the ten heavenly stems (천간), and I’m currently working through the twelve earthly branches (지지) and the twelve life stages (12운성).
Starting tomorrow, I’ll be starting a series of posts summarizing Day Pillar. Starting with the Gapja Ilju (甲子日柱), I’ll analyze all 60 combinations and post them one by one. It’s going to be quite a journey. Think of it as a daily advent calendar, but instead of chocolate, you’ll gain in-depth insights into Korean astrology!
I know this might seem like I’m putting the cart before the horse, but here’s the thing – when most people first discover Korean saju reading, the day pillar is what hooks them. It’s like your astrological DNA, and once you understand yours, everything else starts falling into place.
Your encouragement and feedback in the comments really fuel this project, so please don’t hesitate to share your thoughts, ask questions, or even challenge my interpretations. That’s how we all learn and grow together.
It’s going to be quite a journey, and honestly, I’m both nervous and excited about this ambitious project. Your support and feedback would mean the world to me!
Let’s start with the basics.
Understanding the Four Pillars of Destiny (Korean Saju Reading)
You’ve probably heard the Korean phrase “사주팔자” (saju-palja) before. This term, which literally means “four pillars, eight characters,” is the foundation of Korean astrology and fortune telling.
The core concept of Korean Saju reading is beautifully simple yet profound: a person’s destiny and personality can be understood through the year, month, day, and hour of their birth. Each of these time periods carries specific energies and characteristics from the Five Elements (Wood, Fire, Earth, Metal, Water) and Yin-Yang theory.
Think of it like this – if Western astrology uses planets and constellations, Korean astrology uses the cosmic energies present at the exact moment you took your first breath.
The term “Four Pillars” comes from these four time pillars:




- Year Pillar (연주/年柱) – represents your ancestry and early life
- Month Pillar (월주/月柱) – governs your career and social relationships
- Day Pillar (일주/日柱) – reveals your core personality and marriage
- Hour Pillar (시주/時柱) – indicates your children and later life
Each pillar consists of two characters:

- Heaven (천간/天干) – the Heavenly Stem above
- Earth (지지/地支) – the Earthly Branch below
This gives us eight characters total – hence “팔자” (eight characters). You know that Korean expression “아이고, 내 팔자야!” (“Oh, my fate!”)? Now you know exactly where it comes from!
Why the Day Pillar Matters Most in Korean Fortune Telling
Here’s where Korean Saju reading gets really interesting. While all four pillars matter, the Day Pillar holds special significance in modern Korean astrology practice.
Let me show you an example. If someone was born on August 15, 1994, their Day Pillar would look like this:

- The Heavenly Stem is 癸 (Gye – Yin Water)
- The Earthly Branch is 酉 (Yu – Rooster / Metal)
✨ Therefore, this person’s Day Pillar is 계유 (Gye-yu).
People born on Gye-yu days are said to have sharp minds, strong discernment, and a refined sense of beauty. They may also have a tendency toward perfectionism and a sharp tongue if unbalanced.
This is the foundation of what we call Day Pillar Theory in Korean Saju.
But why focus on the Day Pillar instead of the others?
You might wonder – if there are Day Pillar theories, what about Year, Month, and Hour Pillar theories?
The answer is fascinating: They existed in ancient times, but modern Korean Saju focuses primarily on the Day Pillar.
In ancient Chinese astrology, the Year Pillar was crucial – that’s where concepts like the “Three Calamities” (삼재) come from. You might still hear older generations talking about animal zodiac characteristics or avoid certain years due to 삼재.
However, since the Ming Dynasty, Korean fortune telling and Chinese astrology evolved to center around the Day Pillar – specifically, the Heavenly Stem of the Day Pillar, called the “Day Master” (일간/日干).
Think of it this way: in Western astrology, your sun sign is your core identity. In Korean Saju, your Day Master is your essential self.
The Day Master – Your Core Identity in Korean Astrology
In modern Korean Saju reading, the Day Master represents “you” – your identity, ego, personality, and fundamental nature. Everything else in your chart is interpreted in relation to this central point.
The Earthly Branch directly below the Day Master (called 일지/日支) represents your spouse palace – it reveals insights about your marriage partner and intimate relationships.
Since both “you” and your “spouse” are contained within the Day Pillar, it naturally becomes the most important pillar for personal readings. This is why Day Pillar theory became the cornerstone of Korean astrology interpretation.
Understanding your Day Pillar is like having a personality profile that’s more nuanced than MBTI, more specific than blood type personality theories (popular in Asia), and more personalized than Western zodiac signs.
Beyond Superstition – The Real Value of Korean Saju
Here’s something important I want to address. You might still hear people making broad generalizations:
- “Tiger-born women are believed to have strong energy that can disturb family harmony.”
- “People born in the Year of the Snake are hard to read—they keep their true feelings hidden.”
- “Those born in the Year of the Ox are destined to work hard their entire lives.”
- “People born in the Year of the Horse are unpredictable—you never know which way they’ll go.”(In particular, women born in the Year of the Horse are traditionally believed to have strong and overpowering energy. Because of this belief, birth rates significantly dropped in Horse years like 1906 and 1966.)
Please don’t take these animal zodiac generalizations seriously. While the birth year does influence your overall chart, modern Korean astrology practitioners agree its impact is minimal compared to your Day Pillar.
The real value of Korean fortune telling lies in understanding the complex interactions between all elements of your Four Pillars, with the Day Pillar as your starting point.
When you understand your Day Master and Day Pillar, you’re less likely to be misled by fortune tellers who make vague, sweeping predictions. Knowledge is power, especially when it comes to understanding yourself.
How Korean Saju Compares to Western Astrology
If you’re familiar with Western astrology, here’s a helpful comparison:
Western Astrology | Korean Saju |
12 zodiac signs | 60 Day Pillars |
Sun sign = core identity | Day Master = core identity |
Based on birth month | Based on exact birth day |
Planetary influences | Five Element energies |
Houses for life areas | Four Pillars for life stages |
The beauty of Korean astrology lies in its precision. While Western astrology gives you one of 12 sun signs, Korean Saju offers 60 different Day Pillar combinations, each with unique characteristics.
The 60-Day Cycle in Korean Fortune Telling
One fascinating aspect of Korean Saju is its cyclical nature. Unlike Western linear time concepts, East Asian philosophy views time as circular and repetitive.
The Day Pillar follows a 60-day cycle. This means:
- Today’s Day Pillar will repeat again in exactly 60 days
- Someone born today and someone born 60 days from now share the same Day Pillar
- This creates meaningful patterns and connections across time
Similarly, the Year Pillar follows a 60-year cycle, which is why traditional Korean culture celebrates the 60th birthday (회갑/hoegap) as a major milestone – you’ve completed one full cosmic cycle!
