How to Read a Saju Chart: Stems, Branches, and Your Day Master

A chart has four columns — the pillars of your birth year, month, day, and hour — and two rows. The top row holds the Heavenly Stems (천간); the bottom row holds the Earthly Branches (지지). Eight cells, eight characters: your palja.

Each pillar governs a domain of life. Read from right to left in the traditional layout: the year pillar covers ancestry and early life; the month pillar covers career, parents, and your social prime; the day pillar covers the self and marriage; the hour pillar covers children, inner life, and later years.

The stems are the five elements, each split into a yang and a yin form — ten in all. Yang Wood (甲) is the tall tree; yin Wood (乙) the flexible vine. Yang Fire (丙) is the sun; yin Fire (丁) the candle flame. Yang Earth (戊) is the mountain; yin Earth (己) the cultivated field. Yang Metal (庚) is raw ore; yin Metal (辛) the finished jewel. Yang Water (壬) is the ocean; yin Water (癸) the morning dew.

These images are not decoration — readers genuinely reason with them. A yang Earth person weathers pressure like a mountain; a yin Water person permeates quietly. Learning your own stem’s image is the fastest way into your chart.

The branches are better known in the West as the zodiac animals: Rat (子), Ox (丑), Tiger (寅), and onward through Pig (亥). In serious practice, each branch matters less as an animal and more as a bundle of elemental energy tied to a season and time of day — 子 is deep midnight and the peak of Water; 午 is high noon and the peak of Fire.

Branches also conceal “hidden stems” — secondary energies inside each branch that a full reading takes into account. This is one reason two charts with similar surfaces can read very differently.

The single most important character in your chart is the stem of your day pillar — the day master (일간). Every other character is interpreted relative to it. Elements that feed your day master act as resources; elements it produces are your output and talent; elements it controls are wealth; elements that control it are discipline and career pressure; elements that match it are peers and rivals.

This relational reading is the engine of saju. The question is never “is Fire good?” but “what is Fire doing to this day master, in this season, in this company?”

Take the chart 甲子 (year), 丙午 (month), 戊申 (day), 庚子 (hour) — the example chart we use across this site. The day master is 戊, yang Earth: the mountain. Born in the 午 month — high summer, peak Fire — this Earth is strongly warmed and supported, since Fire creates Earth.

The hour stem 庚 (yang Metal) is what this Earth produces: talent and output, sharpest under pressure. And the two 子 branches — deep Water — are what Earth controls: the wealth element, appearing twice. A reader would see a steady, quietly driven person whose talents crystallise into tangible results, and would then weigh the tensions: 子 and 午 clash, midnight against noon, suggesting a life that must balance public heat with private depth.

That is one paragraph of what a full reading develops across seven life areas — but it shows the method: images, elements, and relationships, all anchored to the day master.
