Bias Match

Jaehyun's zodiac sign, Chinese zodiac and element (BOYNEXTDOOR)

Jaehyun's zodiac sign is Sagittarius. Jaehyun was born in the Year of the Goat (2003, a Water Goat year); Jaehyun's saju day master is 辛 Sin, Yin Metal.

Jaehyun of BOYNEXTDOOR was born on Dec 4, 2003. From that public date we can work out three of the four saju pillars, a Chinese zodiac animal and a Western sun sign.

Day master

辛 Sin · Yin Metal

The Cut Jewel, the Bias Match emblem for 辛 Sin

Jaehyun'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

Jaehyun's three pillars

Three known pillars (the hour is not public)
YearMonthDayHour
Stem癸 Gye · Water癸 Gye · Water辛 Sin · MetalUnknown
Branch未 Mi (Goat) · Earth亥 Hae (Pig) · Water亥 Hae (Pig) · WaterUnknown

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 Gye-Mi (癸未), month Gye-Hae (癸亥) and day Sin-Hae (辛亥).

Jaehyun's zodiac animal is the Goat, from the year branch 未.

Born on the same day: Doyoung (TREASURE), so that three-pillar chart is the same as Jaehyun's. Only the groups and the comparisons below differ.

On Dec 4, 2003 the sun was in Sagittarius, a fire sign.

The moon stayed in Aries all day.

Five elements

Five elements in Jaehyun's chart

木 Wood 0
火 Fire 0
土 Earth 1
金 Metal 1
水 Water 4

Counting the six characters of the three known pillars: Wood 0, Fire 0, Earth 1, Metal 1, Water 4.

Water is the most common element, and Wood and Fire don't appear at all.

Weighing the month branch most, the rest of the chart gives this Metal day master less than average support, so in saju terms the balancing element is Metal.

The most frequent ten-god family in the chart is the output stars, read as expression and making things (4 of the 5 characters counted).

Inside the group

Elements in common inside BOYNEXTDOOR

Inside BOYNEXTDOOR, the chart most similar to Jaehyun's by elements belongs to Riwoo and Leehan (Riwoo: their Metal and Earth day masters sit side by side in the generating cycle, and their fire and air sun signs make a complementary pair; Leehan: their Metal and Water day masters sit side by side in the generating cycle, and their fire and air sun signs make a complementary pair).

The most different belongs to Sungho: both have Metal day masters, and their fire and earth 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.
