Heavenly Stem 06 of 10 · 天干

己

Ji

jǐ

Ji is the yin expression of the Earth phase. In a pillar it supplies phase and polarity; the Earthly Branch beside it supplies the animal and the twelve-position time coordinate.

A late-summer landscape of terraces, grain fields and an earthen courtyard
The turn of each season · CentreThis landscape visualises the traditional seasonal and directional correspondences of Earth. Ji's yin position is supplied by the stem itself.

One sign, one fixed coordinate

What stays fixed for Ji

Wherever 己 appears—year, month, day or hour—it remains Yin Earth. Its position in a chart changes; these identities and stem-to-stem partners do not.

Sequence position
6 of 10

After 戊 Wu; before 庚 Geng.

Five Combination · 五合
甲 Jia

The reciprocal partner five positions away in the stem sequence.

Fixed clash
癸 Gui

The opposing stem named by the fixed reference table.

Six meetings in sixty positions

Every Ji pillar in the cycle

The ten stems and twelve branches advance together. 己 therefore meets six branches before the sixty-position sequence returns to its opening pair.

When 己 is the Day Master · 日主

How Ji names all ten stem relationships

As the day stem, 己 becomes the comparison point. The target stem's phase selects one of five relationship pairs, then its polarity selects the named member of that pair.
