Earthly Branches Dictionary

The branches are the twelve lower characters of the four pillars, and they also mark the zodiac animal, the month and the hour. Each one holds stems inside it (hidden stems), which are read together when setting the ten gods.

The earthly branches (jiji, 地支) are twelve characters: Ja (子)·Chuk (丑)·In (寅)·Myo (卯)·Jin (辰)·Sa (巳)·O (午)·Mi (未)·Sin (申)·Yu (酉)·Sul (戌)·Hae (亥). They form the lower characters of saju's four pillars and correspond to the twelve zodiac signs.

Earthly branches represent the energy of earth, marking seasons, months, and hours. Each contains heavenly stems (hidden stems), which are also used to identify Ten Gods relationships.

Ten God classifications and Day Master strength assessments use the main hidden stem. The table follows the monthly energy divisions (residual · middle · main), with the main stem listed first.

Traits

Among the twelve branches, In·Myo are Wood, Sa·O are Fire, Sin·Yu are Metal, Hae·Ja are Water, and Jin·Sul·Chuk·Mi are Earth. There are four Earth branches because the final month of each season acts as a bridge to the next.

Earthly branches mark months and hours. The In month, beginning at the Start of Spring solar term around February, is the year's first month, and the Ja hour runs from 11 p.m.~1 a.m. Your month branch therefore indicates your birth season, while your hour branch indicates your birth time.

Earthly branches have more varied relationships than heavenly stems. These include Six Harmony (Ja-Chuk·In-Hae·Myo-Sul·Jin-Yu·Sa-Sin·O-Mi), Three Harmony (Sin-Ja-Jin Water group·Hae-Myo-Mi Wood group·In-O-Sul Fire group·Sa-Yu-Chuk Metal group), the six Clashes (Ja-O·Chuk-Mi·In-Sin·Myo-Yu·Jin-Sul·Sa-Hae), and Punishment·Destruction·Harm·Resentment. Combinations suggest binding together, while clashes suggest movement through collision.

Seowoon's engine uses a hidden-stem table organized by the traditional divisions of monthly energy (wollyul bunya: residual·middle·main energy). It uses the main energy's stem to determine Ten Gods relationships and Day Master strength. The table below shows those values.

A common misconception

People often say, “Matching zodiac signs mean good compatibility”, but your zodiac sign is just your year branch, one of the eight characters in your chart. Compatibility readings give more weight to combinations·clashes between your day branches, the partner seats, and the relationship between your Day Masters.

Frequently asked questions

When does the zodiac sign change?

In saju, the year begins at the Start of Spring (Ipchun), around February 4 on the solar calendar, rather than January 1 or Lunar New Year. If you were born before then, your zodiac sign belongs to the previous year.

What are hidden stems?

They are heavenly stems tucked inside each earthly branch. For example, In (寅) contains Gap·Byeong·Mu, with Gap Wood as its main, defining energy.

Are clashes between earthly branches bad?

A clash brings movement through friction, so it is read as change·relocation·conflict. It can also break through a blockage. Its meaning depends on where it appears and what energy the chart needs.
