Day master
庚 Gyeong · Yang Metal
Sana's day master is 庚 Gyeong, Yang 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 庚 as raw ore or an axe blade. Bias Match draws it as The Raw Blade.
Chart
Sana's three pillars
| Year | Month | Day | Hour | |
|---|---|---|---|---|
| Stem | 丙 Byeong · Fire | 庚 Gyeong · Metal | 庚 Gyeong · Metal | Unknown |
| Branch | 子 Ja (Rat) · Water | 子 Ja (Rat) · Water | 子 Ja (Rat) · Water | 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 Byeong-Ja (丙子), month Gyeong-Ja (庚子) and day Gyeong-Ja (庚子).
Sana's zodiac animal is the Rat, from the year branch 子.
On Dec 29, 1996 the sun was in Capricorn, an earth sign.
The moon moved from Leo into Virgo during the day, so without a birth hour the moon sign can't be pinned down.
Five elements
Five elements in Sana's chart
Counting the six characters of the three known pillars: Wood 0, Fire 1, Earth 0, Metal 2, Water 3.
Water is the most common element, and Wood and Earth 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 Earth.
The most frequent ten-god family in the chart is the output stars, read as expression and making things (3 of the 5 characters counted).
Inside the group
Elements in common inside TWICE
Inside TWICE, the chart most similar to Sana's by elements belongs to Jeongyeon: their Metal and Water day masters sit side by side in the generating cycle, and their earth and water sun signs make a complementary pair.
The most different belongs to Tzuyu: their Metal and Fire day masters form a checking pair, and their earth and air 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.
