庚午

Gyeong-O day pillar

Yang Metal over the Horse경오일주 · BaZi: Geng Wu

A blade being tempered in the forge. A disciplined, principled nature that is shaped and proved by pressure.

The picture

Gyeong-O is raw metal in the fire. The Horse’s Fire controls Yang Metal, and that is exactly what makes metal useful: without the forge there is no blade. This pillar cares about honour, rules and doing things properly, and it tends to live under some pressure, much of it self-imposed. It is also more charming than it thinks, and more visible.

The Day Master sits on the element that controls it, in the opposite polarity. Discipline and a sense of duty are built in. In a female chart tradition reads the husband star sitting in the spouse palace as a favourable sign for marriage.

These are the facts every Gyeong-O chart shares, whatever the other three pillars hold. They are taken from the same engine that calculates your chart.

Strengths

  • Integrity that holds when no one is watching.
  • Decisiveness: once the facts are in, it acts.
  • A way of getting better under hardship.

What to watch

  • Self-criticism that never lets up.
  • Rigidity about how things should be done.
  • A quick temper, followed by burnout.

In relationships

Gyeong-O is drawn to people it can respect. It is dutiful and serious in relationships and needs a partner who helps it put the armour down.

At work

Public service, law, the military, management, engineering and work with metal or machinery. It suits clear standards and real responsibility.

A day pillar is one of four. Two people born on a Gyeong-O day in different months and hours have different charts: the season decides how strong the Day Master is, and the other pillars add their own ten gods and interactions. Read this page as the starting point, then look at the whole chart.

Questions people ask

What does the Gyeong-O day pillar mean?
Gyeong-O (庚午) is Yang Metal over the Horse: a disciplined, principled nature that is shaped and proved by pressure.
How do I know if Gyeong-O is my day pillar?
The day pillar comes from a sixty-day cycle and from true solar time at your birthplace, so it cannot be worked out from your birth year or zodiac animal. Calculate your chart: if the Day column shows 庚午, this is your pillar.
What is 庚午 called in Chinese BaZi?
Geng Wu. It is the same pillar. Korean Saju reads the characters as Gyeong-O and calls it Gyeongo ilju (경오일주); BaZi sources write Geng Wu in pinyin.
Which life stage and void branches go with Gyeong-O?
On its own seat the Day Master is at the Bath stage (沐浴). The infant is washed: exposure, charm, instability. Associated with attraction and with youthful mistakes. The void branches for this pillar are 戌 Sul (Dog) and 亥 Hae (Pig). The strength of the whole chart depends mostly on the birth month, not on this stage alone.
