The 10 Day Masters in Saju: All Five Elements, Yang and Yin
By Saju Unni · Updated August 10, 2026 · 6 min read
The ten day masters are the ten heavenly stems placed in the day-master seat of a saju chart. Each combines one of the five elements with yin or yang, giving ten distinct starting languages for temperament: growth, expression, grounding, structure, or reflection, each with an outward or inward style.
The ten day masters: five elements, yin and yang
A day master is one of 10 stems: five elements multiplied by two polarities. The stem at the top of your day pillar stands for you in the chart; the remaining seven characters are read in relation to that reference point. Start with what a day master (ilgan) is, then use the descriptions below as a first sketch rather than a finished portrait.
Yang tends to move outward, initiate, or take visible space; yin tends to refine, respond, and work through detail. Neither side is louder, stronger, or better. The pair simply gives each element two ways of showing up.
Yang Wood (Gapmok, 갑목, 甲)
Yang Wood day masters tend to be direct, growth-minded, and willing to start before every detail is settled. Gapmok (갑목, 甲) is the yang Wood stem, traditionally pictured as a tall tree: upright, reaching, and difficult to hurry once rooted. That can read as principled leadership or as stubbornness when a change of plan asks for more bend.
Yin Wood (Eulmok, 을목, 乙)
Yin Wood day masters tend to be adaptable, tactful, and alert to the social weather around them. Eulmok (을목, 乙) is yin Wood, closer to a vine, flower, or cultivated plant than a single tree. The tendency favors finding a route around an obstacle, building influence gradually, and noticing where care or adjustment is needed.
Yang Fire (Byeonghwa, 병화, 丙)
Yang Fire day masters tend to be open, energizing, and comfortable making an idea visible. Byeonghwa (병화, 丙) is yang Fire, often compared with sunlight: broad, warming, and hard to hide. Enthusiasm can make other people feel included; too much exposure or speed can leave little room for quieter signals.
Yin Fire (Jeonghwa, 정화, 丁)
Yin Fire day masters tend to be observant, expressive in a selective way, and sensitive to atmosphere. Jeonghwa (정화, 丁) is yin Fire, traditionally pictured as a lamp or candle flame. The tendency leans toward focused warmth, taste, and careful timing rather than broadcasting every feeling at once.
Yang Earth (Muto, 무토, 戊)
Yang Earth day masters tend to be steady, protective, and drawn to carrying the bigger load. Muto (무토, 戊) is yang Earth, the image of a mountain or wide plain. Reliability is the gift; the same instinct can turn into taking on everyone else's weight before checking whether help was actually requested.
Yin Earth (Gito, 기토, 己)
Yin Earth day masters tend to be practical, receptive, and good at making conditions workable for other people. Gito (기토, 己) is yin Earth, often pictured as tended soil. The tendency favors cultivation, preparation, and useful detail, with a watch-out for over-managing small concerns that could be left alone.
Yang Metal (Gyeonggeum, 경금, 庚)
Yang Metal day masters tend to be decisive, candid, and motivated by a clear standard. Gyeonggeum (경금, 庚) is yang Metal, the image of raw ore or an unshaped blade. The directness can cut through confusion and protect a boundary; a softer delivery often helps the same clarity land well.
Yin Metal (Singeum, 신금, 辛)
Yin Metal day masters tend to be precise, discerning, and attentive to what needs refining. Singeum (신금, 辛) is yin Metal, traditionally compared with jewelry, a needle, or a finished blade. The tendency favors edit, judgment, and craft, while high standards can become tiring when every rough edge feels urgent.
Yang Water (Imsu, 임수, 壬)
Yang Water day masters tend to be curious, mobile, and ready to follow a wide field of possibilities. Imsu (임수, 壬) is yang Water, the image of an ocean or large river. Big-picture thinking and easy movement between ideas are strengths; a chosen bank or deadline gives that current somewhere useful to go.
Yin Water (Gyesu, 계수, 癸)
Yin Water day masters tend to be perceptive, flexible, and unusually aware of nuance. Gyesu (계수, 癸) is yin Water, associated with rain, dew, or mist. The tendency favors listening, research, and responsive intelligence, with a pause needed when reading every signal starts to crowd out a simple decision.
Why the same day master can read so differently
The same day master can look very different when the rest of the chart changes its support. A Gapmok chart born in spring with Wood roots has a different balance from Gapmok born in autumn under heavy Metal, even though both begin with 甲. Strong and weak day master explains how season, roots, and the other characters make that difference.
The ten descriptions name a useful first tendency, not a label to perform. A free saju chart finds your day master from your birth data, shows the five-element balance around it, and gives you a concrete place to begin your own self-reflection.
FAQ
- What are the 10 day masters in saju?
- The ten day masters are the ten heavenly stems used in the day-master position: Yang and Yin Wood, Fire, Earth, Metal, and Water. Each stem gives a reading its reference point, because the seven remaining characters are interpreted by how they support, drain, or regulate that one stem. The ten are starting tendencies, not ten fixed personality boxes.
- How do I find my day master?
- Your day master is the heavenly stem at the top of the day pillar, the column calculated from your date of birth. A calendar-based saju chart computes all four pillars and labels that top day-stem character for you. Birth time is useful for the hour pillar, but the day master itself comes from the birth date.
- What is the difference between Yang and Yin day masters?
- Yang and yin are two expressions of the same element, not a quality ranking. Yang stems tend to read as outward, initiating, or visible; yin stems tend to read as responsive, refining, or subtle. A Yang Wood and a Yin Wood day master both begin with Wood, yet their typical pace and style are different.
- Why do two people with the same day master seem different?
- The same central stem sits inside different seasons and different company. A stem with roots, resource, and a supportive birth season reads differently from the same stem with little support and heavy demand. Day-master strength and the five-element balance give the type its real context.
- Is one day master better than another?
- No. Every day master has a useful tendency and a possible overshoot: directness can become rigidity, while sensitivity can become over-editing. Saju is most useful when the pattern becomes a choice you can notice and work with, rather than a ranking of people.
