How to Read Your Saju — The Order for Reading the Eight Characters

Saju (the Four Pillars of Destiny) turns the year, month, day, and hour of your birth into eight characters — a Heavenly Stem and Earthly Branch (ganzhi) for each of the four pillars. The standard order for reading those eight characters is to start with the Day Master (日干), the character that stands for you, then look at the distribution of the Five Elements (Wood, Fire, Earth, Metal, Water), the Ten Gods (十星) relationships the other characters form with you, and finally the flow of time through your Luck Pillars and Annual Luck. Deeper factors — symbolic stars, rootedness, and palace positions — come last, read as reference for the overall grain of a chart. What matters most is treating Saju as a mirror for looking back at yourself, not as a scorecard or a fixed fate.

In what order should you read the Four Pillars?

If you're new to Saju, it's easy to feel lost about which of the eight characters to look at first. Drawing on the classical texts and the standard theory of the Five Elements, here is the most basic order for reading a chart.

1. Find your Day Master (日干): Among the eight characters, the Heavenly Stem of your day of birth is called the Day Master. In a reading it stands for you, and it becomes the reference point for everything else. Knowing the character of your Day Master is the first step toward understanding your chart — each Day Master carries its own basic disposition. And because this is the first button in the row, if it's fastened wrong everything above it comes loose. Getting the Day Master right matters, yet around midnight (the late-night Zi hour) or during old daylight-saving windows, general-purpose AI often gets even the Day Master wrong. Gwiraedang pins it down with astronomical calculation — true solar time and solar terms handled by its own Ten-Thousand-Year (perpetual) calendar engine, deterministically.
2. Look at the distribution of the Five Elements (五行): Check how Wood, Fire, Earth, Metal, and Water are spread across the eight characters. Where an element runs abundant or scarce, you catch a glimpse of the balance of your energies. This isn't about tallying a score of more versus less — it's about seeing which energies are strong and which are weak. For what each element means at its root, What the Five Elements Are goes into more detail.
3. Understand the Ten Gods (十星) relationships: The Ten Gods describe how the other characters relate to you, measured from your Day Master. They sort into ten roles — Companions (比劫), Output (食傷), Wealth (財星), Authority (官星), and Resource (印星) among them — and each one points to tendencies across different areas of life: temperament, money, work, family ties, and more. It's worth exploring what each of the Ten Gods means in depth.

These three form the basic skeleton of a chart, and they go a long way toward understanding your innate temperament and potential. One step deeper, you can take the reading further with a strong or weak Day Master — how much support the Day Master draws from the characters around it — and with the useful god, the favorable element you lean on to bring the energies back into balance.

What about the flow of time and the deeper factors in a reading?

Saju isn't a fixed table of fate — it's a living mirror that shifts and moves with time. Once you have the basic skeleton, you look at the flow of time and the factors that sit deeper.

1. Reading the Luck Pillars (大運) and Annual Luck (歲運): Your chart isn't frozen; it's shaped by the Luck Pillars that turn over every ten years and the Annual Luck that changes year to year. The Luck Pillars show the broad current and direction of a life, while the Annual Luck points to the tendency of specific events or shifts in circumstance a given year may bring. Following that flow lets you consider when, in which area, and what kind of shift in energy might show up. You can trace your own Luck Pillars and Annual Luck with a Ten-Thousand-Year (perpetual) calendar.
2. Reference the deeper factors — symbolic stars (神殺), rootedness (通根), palace positions (宮位), and more: Symbolic stars mark a special leaning of energy that arises from certain combinations of characters; rootedness asks whether the energy of a Heavenly Stem has taken root in the Earthly Branches below; and palace positions read what each character's seat — the year, month, day, or hour — suggests about family ties and the seasons of a life. These are reference material that makes a reading richer, and they're used to understand particular tendencies rather than to pronounce a fixed fate.

Even when you don't know your exact birth time, you can still confirm your Day Master and Day Pillar (日柱) — so with only the Hour Pillar (時柱) missing, you can still make out a great deal of a chart. Reading your Saju is a process of understanding yourself and turning it into a chance to grow — and understanding what Saju is at its core only deepens that.

Hold it up to your own chart

It's worth holding everything you've just read up against your own chart. First, check what your Day Master is — the character at the center of your Saju. Then quietly count which way the Five Elements lean among your eight characters. You're not trying to get a right answer; it's enough to notice, ah, this grain runs through me. Which energy is most abundant, and which one is missing?

FAQ

If I don't know my birth time, can I still read my Saju? Yes. Even without an exact birth time you can still read your Saju — you simply lose the two characters of the Hour Pillar (時柱), and the remaining six characters of the Year, Month, and Day Pillars still carry plenty of information.

If my chart has a "bad" character or an inauspicious star, does that mean I'm doomed to misfortune? No. Having a particular character or an inauspicious symbolic star in your chart doesn't lock in an unlucky fate. Saju is a tool for self-reflection — a way to spot your weak points, shore them up, and turn them into room to grow.

Saju is a reference for self-reflection and growth, not a fixed fate.
