What does the Gap-Sin day pillar mean?

Gap-Sin (甲申) is Yang Wood over the Monkey: a principled, restless nature sharpened by pressure and good in a crisis.

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

What is 甲申 called in Chinese BaZi?

Jia Shen. It is the same pillar. Korean Saju reads the characters as Gap-Sin and calls it Gapsin ilju (갑신일주); BaZi sources write Jia Shen in pinyin.

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

On its own seat the Day Master is at the Extinction stage (絕). The lowest point, where the old cycle is cut off before the new one forms. Rootlessness and total change. The void branches for this pillar are 午 O (Horse) and 未 Mi (Goat). The strength of the whole chart depends mostly on the birth month, not on this stage alone.

The picture

Gap-Sin is a tree growing out of rock. The Monkey’s Metal controls Yang Wood, and the tree has no root here, so this pillar lives with tension and with change. It is disciplined and capable when things go wrong. The Monkey also holds water, which turns the axe’s pressure into nourishment. Gap-Sin people often move, change fields or work far from where they began.

What the pillar is made of

The Day Master sits on the element that controls it, in the same polarity. Pressure is built into the seat: this pillar is used to being tested and often has a strong-willed partner. Readers look for something in the chart that handles the pressure, an Eating God or a Resource.

These are the facts every Gap-Sin 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-Sin 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.
