Traditional Saju Basics - Day Stem, Month Branch, and Five Elements in One Flow
A practical introduction to traditional saju: the eight-character chart, day stem, month branch, and five-element balance. Built so beginners can grasp their core structure in about 10 minutes.
What is the Eight-Character Saju Chart?
Saju is built from four pillars: year, month, day, and hour. Each pillar has one heavenly stem and one earthly branch, making eight characters in total. That is why it is called the four pillars and eight characters, and this structure is the base for reading personality and timing.
For example, a birth time like 1990-03-15 14:30 maps to a full chart through calendar and solar-term rules. You do not need to memorize Chinese characters yourself because the chart is calculated automatically.
Why the Day Stem Matters Most
In the chart, the heavenly stem of the day pillar, called the day stem, is the core reference point. It represents you, and the other seven characters are interpreted in relation to this center.
There are ten possible day stems: Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, and Gui. Each has a different behavioral tone, so people respond to similar situations in different ways.
If you do not know your day stem yet, you can check it in about one minute through the free preview. For a quick stem-by-stem read, continue to Quick Guide to the 10 Day Stems.
Why the Month Branch Comes Next
If the day stem is your core self, the month branch often shows how that self appears in the social world. Work style, collaboration pattern, and relationship tone are strongly reflected here.
The month branch is one of the 12 earthly branches. Reading day stem plus month branch together gives the clearest practical picture in most cases.
For first-pass interpretation, this pair alone can explain the majority of your core tendency.
Five-Element Balance - Excess and Deficiency
Every stem and branch belongs to one of the five elements: Wood, Fire, Earth, Metal, and Water. The balance among these elements defines your default energy pattern.
When one element is missing or overactive, repeated behavior patterns tend to appear in decisions, emotions, and recovery cycles.

A Simple Reading Order
If you are new to saju, use this order: identify your day stem, check your month branch, inspect five-element balance, read the ten gods, then review major luck cycles.
This order keeps interpretation practical and avoids information overload.
In Unwol, these steps are analyzed automatically so you can read your own result while following the guide articles.
