How to Read Your Saju Chart: A Beginner's Walkthrough
By Saju Unni · Updated August 10, 2026 · 7 min read
Reading a saju chart takes four passes: find the day master, count the five elements, read what each pillar covers, then notice how the characters interact. The grid holds only eight characters, so most of the work is knowing which box answers which question — what is saju covers the system itself.
The 60-second orientation: what the 4×2 grid is
A saju chart is eight characters in four columns and two rows. Each column is a pillar built from one unit of your birth moment — year, month, day, hour. The Encyclopedia of Korean Culture describes saju in exactly these terms: birth year, month, day, and hour written as ganji (간지, 干支) pairs.
The two rows are different alphabets:
- Top row — ten heavenly stems (천간, 天干): five elements in yang or yin form. The visible, outward layer.
- Bottom row — twelve earthly branches (지지, 地支): the characters tied to the zodiac animals. The grounded, situational layer.
Column order varies: Korean charts often print hour-first from the left, English calculators year-first — read the labels first. Stems and branches covers both alphabets.
Step 1 — Find your day master
The day master (일간, 日干) is the top character of the day pillar, and it stands for you. Every other character is read in relation to it, so this box comes first.
Ten day masters exist: five elements × two polarities. Yang Wood (甲) reads as upward and structural, Yin Wood (乙) as flexible and adaptive — same element, different strategy. None outranks another. Your day master, explained has a read for each.
Step 2 — Count the five elements across all eight characters
Tally the eight characters by element — wood, fire, earth, metal, water. Eight characters over five elements averages 1.6 each, so 3 or more reads as dominant and 0–1 as low. Branches also carry hidden stems (지장간, 支藏干), so a surface count is an approximation.
What a low or missing element means
A low element names a quality you reach for less by default, not a defect. Low fire tends to read as running warm inside without broadcasting it — a muscle worth using deliberately rather than a hole in the chart.
What a dominant element means
A dominant element names your default setting — heavy metal tends to read as decisiveness and clean edges, heavy water as constant processing. The five elements (ohaeng) covers how they feed and check each other.
Step 3 — Read each pillar's sphere
Each pillar maps to a life sphere and, traditionally, a life stage. Ask a question, then read the pillar that owns it.
What the year pillar means in saju
The year pillar covers roots and the wider social world: family background, inherited context, how you register outside your inner circle. Its branch is the familiar zodiac animal — one character out of eight, shared with everyone born that year.
What the month pillar means in saju
The month pillar covers career drive, growth, and the environment you developed in — work, ambition, output. Most schools weight it second only to the day pillar: the month branch sets the season of birth, which decides much of whether your day master is supported or stretched.
What the day pillar means in saju
The day pillar covers the core self and closest relationships: the stem is you, and the branch below is the traditional spouse palace (배우자궁, 配偶者宮), read for how you behave in partnership. It is the most-read pillar in Korean practice.
What the hour pillar means in saju
The hour pillar covers private life — what happens behind closed doors, later chapters, the parts most people never see. A known birth time is required, so a chart without one drops to three pillars: 75% intact, narrower rather than empty.
Step 4 — Notice the interaction tags
Interaction tags describe relationships between two characters, never a standalone verdict. Two appear first:
- Hap (합, 合) — combination. Two characters bond and pull toward each other, softening or redirecting what either does alone. Reads as attraction and cooperation, sometimes distraction.
- Chung (충, 沖) — clash. Two characters sit opposite and push. Reads as movement and friction: restlessness, relocation, sharp turns.
Neither is bad news. Pure hap can read as comfortable and unchallenged, chung as eventful — a chart with no tension in it is not the goal.
What not to over-read as a beginner
Three habits produce most bad first readings, all from treating a fragment as the whole chart.
- Single characters out of context. One "bad" character means little alone; what matters is whether the other seven offset it.
- Animal-year-only readings. The zodiac animal is one branch out of eight — a doorway, not an answer. See Korean zodiac animals and your saju.
- Absolute statements. Saju describes tendencies, not outcomes — the leaning, and what you can do with it.

FAQ
- Where do I start when reading my saju chart?
- Start with the day master — the top character of the day pillar. It stands for you, and every other character in the grid is interpreted in relation to it. Once that reference point is set, count the five elements across all eight characters, then read each pillar for its own life sphere.
- What does each pillar mean in saju?
- The year pillar covers roots and the wider social world, including family background and how you register with people outside your inner circle. The month pillar covers career drive, growth, and the environment you developed in. The day pillar covers the core self and closest relationships, with the branch below the day master read as the spouse palace. The hour pillar covers private life and later chapters.
- How do I count the five elements in my chart?
- Tally each of the eight characters by element — wood, fire, earth, metal, water. Eight characters spread over five elements averages 1.6 each, so a count of 3 or more reads as dominant and 0–1 reads as low. Note that earthly branches also carry hidden stems, so a surface count of the visible characters is an approximation rather than the final weighting.
- What do hap (합) and chung (충) mean in a saju chart?
- Both describe a relationship between two characters, not a standalone verdict. Hap is a combination, where two characters bond and pull toward each other, softening or redirecting what either would do alone. Chung is a clash, where two characters sit opposite and push, reading as movement and friction. Neither is bad news — a chart with no tension in it is not the goal.
- What do beginners most often get wrong?
- Three things: reading single characters out of context instead of checking whether the other seven offset them, reading the birth-year animal alone when it is one branch out of eight, and phrasing results as certainties. Saju describes tendencies, not outcomes.
