Today's day pillar is 丁丑 (ding chou), a yin Fire day in the sixty-day cycle. The month pillar is 戊戌 (wu xu), governed by the term 寒露 (hanlu).

丑 (chou), the second earthly branch

丑 is the ox branch, frozen ground with things stored in it, the last month of winter rather than the coldest feeling one.

丑 is the second branch: Earth by element, yin by position, ox by animal. Its hours are 01:00 to 03:00 and its month opens at 小寒 (xiaohan) in early January and runs to 立春 (lichun), which makes it the final month of the BaZi year.

It is one of the four earth branches that sit at the seams between seasons, and it is unusually crowded inside. Three stems hide in it: 己 (ji, yin Earth), 癸 (gui, yin Water) and 辛 (xin, yin Metal). The tradition calls that a storehouse, cold ground holding metal and water that will be needed later.

When today's branch is 丑 the day is an ox day. Paired with the ten stems it gives 乙丑 (yi chou), 丁丑 (ding chou), 己丑, 辛丑 and 癸丑, five of the sixty.
