What does the Gap-O day pillar mean?

Gap-O (甲午) is Yang Wood over the Horse: a brilliant, expressive and passionate nature that gives everything it has.

How do I know if Gap-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 甲午, this is your pillar.

What is 甲午 called in Chinese BaZi?

Jia Wu. It is the same pillar. Korean Saju reads the characters as Gap-O and calls it Gapo ilju (갑오일주); BaZi sources write Jia Wu in pinyin.

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

On its own seat the Day Master is at the Death stage (死). Stillness. Not literal death but the end of activity; introspection and endings. The void branches for this pillar are 辰 Jin (Dragon) and 巳 Sa (Snake). The strength of the whole chart depends mostly on the birth month, not on this stage alone.

The picture

Gap-O is wood feeding fire. Yang Wood produces the Horse’s Fire in the opposite polarity, so this pillar pours itself out in words, performance and action. It is charismatic, fast and outspoken. It says what it thinks to whoever is in charge. The tree is the fuel, and Gap-O burns itself to shine. Hidden beside the fire is the earth it produces, which is Gap’s wealth: when the performance finds an audience, it pays.

The Day Master sits on the element it produces, in the opposite polarity. Expression and independence sit in the most personal place of the chart: lively and outspoken at home. In a female chart tradition reads this as a need for a partner who accepts a strong voice.

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

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