What does the Im-O day pillar mean?

Im-O (壬午) is Yang Water over the Horse: a sociable, practical nature with charm, money sense and changeable feelings.

How do I know if Im-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 壬午, this is your pillar.

What is 壬午 called in Chinese BaZi?

Ren Wu. It is the same pillar. Korean Saju reads the characters as Im-O and calls it Imo ilju (임오일주); BaZi sources write Ren Wu in pinyin.

Which life stage and void branches go with Im-O?

On its own seat the Day Master is at the Conception stage (胎). New life forming: potential, plans, things not yet visible. The void branches for this pillar are 申 Sin (Monkey) and 酉 Yu (Rooster). The strength of the whole chart depends mostly on the birth month, not on this stage alone.

The picture

Im-O is water meeting fire. Yang Water controls the Horse’s Fire, and the Day Master combines with the stem hidden there, so this pillar is closely attached to what it wants: money, a partner, a position. The Horse holds both wealth and status for Im, which tradition counts as fortunate. Im-O is lively, likeable and quick. Its moods can swing as fire and water take turns.

What the pillar is made of

Part	In Im-O
Day Master	壬 Im, Yang Water
Day branch	午 O, the Horse
Hidden stems	己 Gi: Direct Officer丁 Jeong: Direct Wealth (main)
Life stage	Conception 胎
Void branches	申 Sin (Monkey), 酉 Yu (Rooster)
Stars it carries	Tanghwa, Hyeonchim

The Day Master sits on the element it controls, in the opposite polarity. Practicality is at the core, and money and home are closely linked. In a male chart tradition reads the wife star sitting in the spouse palace as a favourable sign for marriage.

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

Strengths

Sociability that opens doors.
Financial sense joined to charm.
Versatility: it is at home in many settings.

What to watch

Emotional swings between hot and cold.
Taking on more than it can hold.
Temptation, in money and in love.

In relationships

Romantic and attached, Im-O is devoted to its partner and enjoys courtship. It needs steadiness from the other side.

At work

Business, finance, trade, entertainment and diplomacy.

A day pillar is one of four. Two people born on a Im-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.
