What does the Sin-Sa day pillar mean?

Sin-Sa (辛巳) is Yin Metal over the Snake: a polished, bright and proper nature that wants to be seen at its best.

How do I know if Sin-Sa 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 辛巳, this is your pillar.

What is 辛巳 called in Chinese BaZi?

Xin Si. It is the same pillar. Korean Saju reads the characters as Sin-Sa and calls it Sinsa ilju (신사일주); BaZi sources write Xin Si in pinyin.

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

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 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

Sin-Sa is a gem in the light. The Snake’s Fire controls Yin Metal, and its main stem combines with the Day Master, so this pillar is closely tied to authority, standards and reputation. It is intelligent, well presented and correct. The light that shows the jewel also shows every flaw, and Sin-Sa feels criticism sharply.

What the pillar is made of

Part	In Sin-Sa
Day Master	辛 Sin, Yin Metal
Day branch	巳 Sa, the Snake
Hidden stems	戊 Mu: Direct Resource庚 Gyeong: Rob Wealth丙 Byeong: Direct Officer (main)
Life stage	Death 死
Void branches	申 Sin (Monkey), 酉 Yu (Rooster)
Stars it carries	Bokseong, Hyeonchim

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 Sin-Sa chart shares, whatever the other three pillars hold. They are taken from the same engine that calculates your chart.

Strengths

Polish in manner and presentation.
Intelligence that grasps what is expected.
A sense of propriety others trust.

What to watch

Sensitivity to the smallest criticism.
Vanity about image and standing.
Anxiety under scrutiny.

In relationships

Sin-Sa forms strong attachments and is drawn to people of standing. It wants a relationship it can be proud of in public and safe in at home.

At work

Public-facing professions, finance, beauty, law and administration.

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