Day master
辛 Sin · Yin Metal
Isa's day master is 辛 Sin, Yin Metal. In saju the day master is the stem of the day pillar, and the rest of the chart is read from it.
Saju pictures 辛 as a cut jewel. Bias Match draws it as The Cut Jewel.
Chart
Isa's three pillars
| Year | Month | Day | Hour | |
|---|---|---|---|---|
| Stem | 辛 Sin · Metal | 辛 Sin · Metal | 辛 Sin · Metal | Unknown |
| Branch | 巳 Sa (Snake) · Fire | 丑 Chuk (Ox) · Earth | 卯 Myo (Rabbit) · Wood | Unknown |
Birth hours aren't public, so the hour pillar is left blank and no rising sign is given. The day pillar is worked out for noon, so for a birth close to midnight it could be the previous or next day's.
The three known pillars are year Sin-Sa (辛巳), month Sin-Chuk (辛丑) and day Sin-Myo (辛卯).
Isa's zodiac animal is the Snake, from the year branch 巳.
On Jan 23, 2002 the sun was in Aquarius, an air sign.
The moon stayed in Taurus all day.
Five elements
Five elements in Isa's chart
Counting the six characters of the three known pillars: Wood 1, Fire 1, Earth 1, Metal 3, Water 0.
Metal is the most common element, and Water doesn't appear at all.
Weighing the month branch most, the rest of the chart gives this Metal day master more than average support, so in saju terms the balancing element is Water.
The most frequent ten-god family in the chart is the companion stars, read as self and peers (2 of the 5 characters counted).
Inside the group
Elements in common inside STAYC
Inside STAYC, the chart most similar to Isa's by elements belongs to Yoon and J (Yoon: their Metal and Water day masters sit side by side in the generating cycle, and their air and fire sun signs make a complementary pair; J: their Metal and Water day masters sit side by side in the generating cycle, and their air and fire sun signs make a complementary pair).
The most different belongs to Sumin: their Metal and Wood day masters form a checking pair, and their air and water sun signs make a contrasting pair.
This compares day masters, sun-sign elements and element balance only. It says nothing about how anyone gets along in real life.

Guide
How to read this page
- Day master
- The heavenly stem of the day pillar. In saju the whole chart is read from this stem.
- Three pillars
- Year, month and day, each a stem over a branch. The fourth pillar needs the birth hour, which isn't public.
- Five elements
- Wood, fire, earth, metal and water. Each of the six known characters carries one, and the bars add them up.
- Balancing element
- The element saju would add to even out the chart. It describes the chart's symbols, not the person.
- Ten-god families
- Five groups of relationships between the day master and the other characters: companion, output, wealth, officer and resource.
