Day pillars

The 甲子 Day Pillar

How Saju-Link reads the day pillar 甲子 — what the stems held by the day branch are to the day stem — laid out exactly as its calculation rules have it.

甲子 is day pillar number 1 of the sexagenary cycle

When the stem-branch of the birth day is 甲子, the day stem is 甲 (Wood, Yang) and the day branch is 子 (the Rat). In the sexagenary cycle it is the combination number 1.

Saju-Link calls a person whose day stem is 甲 "Yang Wood (甲)", and the line the result screen shows is: "A tall tree growing straight. Once the direction is set it does not waver, and it would rather endure than bend." This line has nothing to do with the reading below or the scores.

What the stems held by the day branch 子 are to the day stem

The day branch is the spouse position. Read from the day stem 甲, the stems that 子 holds are as follows. The principal stem (癸) is the branch's representative energy.

The spouse position and this day pillar

Traditional myeongri reads the spouse position as Steady Wealth (正財) for men and Authority (正官) for women. With 甲 as the day stem, Steady Wealth is 己 and Authority is 辛.

For men, the spouse position (Steady Wealth) is 己. 己 is not held inside 子.

For women, the spouse position (Authority) is 辛. 辛 is not held inside 子.

The neighbouring day pillars and the characters it is made of

In the sexagenary cycle the previous day pillar is 癸亥 and the next is 乙丑.

It is made of Yang Wood (甲) and 子 (Rat).
