A saju reading follows a fixed order. The reader starts with the day stem, weighs it against the season of birth, decides which element the chart needs, names every other character by its relationship to the day stem, and only then turns to timing. Saju (사주, 四柱) is the Korean name for the Four Pillars, the same system this site calls Ba Zi (八字 bāzì), so the order is the same one we use in Singapore.
This page walks through that order in saju terms and then covers what a good session looks like, and what should make you leave. For what saju is and how it compares to Ba Zi, start at the saju hub.
Before the saju reading: a chart cast correctly
Every reading rests on four pillars cast from the birth date and time, traditionally looked up in a 만세력 (manseryeok, 萬歲曆), the perpetual calendar. Korean births raise a specific time-zone question, which the saju calculator guide covers in full. Assume here that the eight characters are right.
The reading order, step by step
1. 일간: the Day Master
The reader’s first look goes to the 일간 (ilgan, 日干), the heavenly stem of the day pillar. It stands for the person. Everything else in the chart is read against it. The ten possible day stems are profiled in Day Masters, explained.
2. The month branch and the season: strength
Next comes the branch of the month pillar, which records the season of birth. A Fire day stem born in deep winter and one born at the height of summer start from very different temperatures, even with the same stem. The season is the heaviest single factor in the first technical call of the reading: is the day stem strong or weak? Roots in the other branches and support or drain from the surrounding stems complete that judgement, laid out in strong vs weak Day Master.
The classic mistake at this step is counting elements, the 오행 (ohaeng, 五行), instead of weighing them. Three Water characters in a summer chart can matter less than one in a winter chart.
3. 용신: the useful god
From the strength call follows the 용신 (yongsin, 用神), the useful god or favourable element. As a rule of thumb, a strong day stem is helped by the element it produces, the element it controls, and the element that controls it. A weak day stem is helped by the element that produces it and by its own element. The season and the structure of the chart can override this, which is why a careful reader states the yongsin as a reasoned conclusion, not a slogan.
4. 십신: the ten gods
Now every other stem in the chart receives a functional name, the 십신 (sipsin, 十神), also called 십성 (sipseong, 十星): the Ten Gods (十神 shíshén) of Ba Zi. What feeds the day stem is Resource, what it produces is Output, what it controls is Wealth, what controls it is Officer or Seven Killings, and its own element is Friend or Rob Wealth. The assignments are a fixed lookup from the day stem, listed for all ten in the Ten Gods master table.
5. 대운 and 세운: timing comes last
Only once the structure is clear does the reader turn to the 대운 (daeun, 大運), the luck pillars. Each lasts ten years and adds one stem and one branch to the chart. Their direction follows the year stem and the person’s sex, and their starting age follows the number of days from birth to the next or previous jie solar term, depending on that direction; the mechanics are on the luck pillars page. The question for each decade is simple: does it bring the yongsin, or more of what the chart already has too much of?
The finest layer most people need is the 세운 (seun, 歲運), the annual year, read inside the current decade. A difficult year inside a supportive decade is a rough stretch on a good road. The same logic, in Ba Zi vocabulary, is set out in how to read your Ba Zi chart.
Why the order matters
Readings go wrong when timing is read before structure. A clash in next year’s pillar sounds alarming on its own; against a chart that needs what that year brings, it may be a useful year. Saju practitioners also work with 신살 (sinsal, 神煞), the symbolic stars. They are a secondary layer. A reading that leads with them, or with the year animal alone, has skipped the four steps that give them meaning.
What a good saju reading session looks like
In charts we read, a working session has a recognisable shape:
- The chart is on the table. You can see the eight characters, and the reader can point to the character behind each statement.
- The reasoning is shown. The strength call and the yongsin are explained, so you can follow them, question them, and remember them.
- Timing is framed as conditions. Decades and years are described as favourable or demanding for particular kinds of effort, not as events that will happen to you.
- You leave with something written. A summary outlasts a memorable phrase.
- Uncertainty is admitted. If the birth time is unknown or near a boundary, a good reader says what that changes. Where schools differ, they say so.
What to be wary of
The same warning signs appear in saju and Ba Zi alike, in storefront consultancies, 철학관 (cheolhakgwan, 哲學館), and online:
- Fear first. A reading that opens with danger, illness or a failed marriage, before explaining the chart, is selling something.
- The upsell. Talismans, paid rituals or “protection” offered as the answer to a problem the reader has just announced. No character in a chart is fixed by a purchase.
- Verdicts. “You will divorce”, “you will never be rich”. A chart describes tendencies and timing; it does not hand down sentences.
- No working. If the reader cannot show which characters lead to a conclusion, there is nothing to check, and nothing to learn from.
Reading two charts side by side for marriage is its own discipline, covered in saju compatibility. The characters themselves, with their Korean readings, are tabled in saju palja.
Book a saju reading
If you would like the order above applied to your own chart, book a reading: one hour, chart on the table, a written summary afterwards, and no fear-selling.
