Heavenly stem	己 (ji)
Earthly branch	巳 (si)
Day element	Earth 土 (tu)
Polarity	Yin
Month pillar	戊申 (wu shen), governed by 立秋 (liqiu)

Today's day pillar is 己巳 (ji si), a yin Earth day in the sixty-day cycle. The month pillar is 戊申 (wu shen), governed by the term 立秋 (liqiu).

己 (ji), the sixth heavenly stem

己 is yin Earth: the field rather than the mountain, soil that has been worked and is meant to grow something.

Sixth of the stems and Earth in its yin form, 己 is garden soil, the flat cultivated ground. Where 戊 (wu) holds a shape, 己 receives and nourishes, and classical writing gives it the qualities of a good medium rather than a good barrier.

Because it is yin it pairs only with yin branches, giving 己丑 (ji chou), 己巳 (ji si), 己亥 (ji hai) and the rest. 己 is the main hidden stem of 丑 (chou) and 未 (wei), the two earth branches that sit at the seams of winter and summer.

A 己 day reads Earth and yin on the page. Earth days are the ones readers most often find quiet, which the tradition treats as a tempo, a settling pace, not as nothing happening.
