What the Sin Metal Day Master is like
Sin is Yin Metal: jewelry, a polished blade, something already refined. Sin Day Masters tend to have high standards, a sharp eye for quality, and a strong sense of how they want to be seen.
The strength is precision and taste. The blind spot is fragility of pride: a jewel scratches, and Sin can be wounded by careless words or by environments that do not recognize its value.
Sin suits work where finish matters — design, finance, fashion, editing, specialist services — and where its standards are an asset rather than a source of friction.
A Day Master describes temperament, not destiny. Whether these traits help or hurt depends on the rest of the chart — above all, whether Metal is strong or weak in it.
How the ten stems relate to Sin Metal
Saju reads every other character as one of the Ten Gods (十神) relative to your Day Master. For a Sin Metal person, the stems mean this:
| Stem | Element | Ten God for Sin |
|---|---|---|
| Gap Wood (甲) | Yang Wood | Direct Wealth |
| Eul Wood (乙) | Yin Wood | Indirect Wealth |
| Byeong Fire (丙) | Yang Fire | Direct Officer (Authority) |
| Jeong Fire (丁) | Yin Fire | Seven Killings (Pressure) |
| Mu Earth (戊) | Yang Earth | Direct Resource (Support) |
| Gi Earth (己) | Yin Earth | Indirect Resource |
| Gyeong Metal (庚) | Yang Metal | Rob Wealth (Rival) |
| Sin Metal (辛) | Yin Metal | Companion (Friend) |
| Im Water (壬) | Yang Water | Hurting Officer (Expression) |
| Gye Water (癸) | Yin Water | Eating God (Output) |
Sin combines with Byeong Fire (丙) (a stem combination, 天干合) and clashes with Eul Wood (乙) (天干沖).
The twelve branches through Sin's eyes
The Twelve Life Stages (十二運星) show how much footing Sin Metal has in each branch. "Prosperity" and "Peak" are where it stands on its own roots; "Tomb" and "Severance" are where it has the least.
| Branch | Element | Life stage |
|---|---|---|
| Ja (子) · Rat | Water | Birth |
| Chuk (丑) · Ox | Earth | Nurturing |
| In (寅) · Tiger | Wood | Conception |
| Myo (卯) · Rabbit | Wood | Severance |
| Jin (辰) · Dragon | Earth | Tomb |
| Sa (巳) · Snake | Fire | Death |
| O (午) · Horse | Fire | Sickness |
| Mi (未) · Goat | Earth | Decline |
| Sin (申) · Monkey | Metal | Peak |
| Yu (酉) · Rooster | Metal | Prosperity |
| Sul (戌) · Dog | Earth | Coming of Age |
| Hae (亥) · Pig | Water | Bath |

Frequently asked questions
- What does a Sin Metal Day Master mean?
- It means the first character of your day pillar is 辛 (Sin), Yin Metal. Korean Saju pictures it as a jewel or fine blade. Refined, exacting, and quietly proud.
- Which stem combines with Sin Metal?
- Byeong Fire (丙). Its clash partner is Eul Wood (乙).
- Is the Day Master the same as my zodiac animal?
- No. Your animal comes from the year branch and is shared by everyone born that year. The Day Master comes from your birth day, changes every day, and is what Saju actually reads you by.
- How do I know my Day Master in K-Saju?
- Your Day Master (Ilgan) is the Heavenly Stem of your birth day pillar among the 10 stems (Gap/Eul Wood, Byeong/Jeong Fire, Mu/Gi Earth, Gyeong/Sin Metal, Im/Gye Water). Enter your birth year, month, and day in the HeartLoop calculator on this page to compute your exact Day Master and Five Elements ratio in 3 seconds.
- What is my 2027 fortune based on my birth date?
