bing-wu day pillar

Both halves of 丙午 are fire, yang fire set on 午, the Horse. This site's table finds 丁 inside, which is Rob Wealth to 丙, and 己, the Hurting Officer, earth that fire produces. 三命通會 divides this branch between 丙 for seven days and 丁 for twenty-three, and gives no 己.

丙 stands at the height of the twelve stages on 午, the position called Emperor, 帝旺. 三命通會 卷一 tags the entry 羊刃, a term built on the word for blade, and 神峰通考 uses that word for a yang stem meeting its yin counterpart, which describes 丙 against the 丁 inside this branch. A peak on the wheel is a location and settles nothing about a chart as a whole.

The text we have contains an oddity. The 納音 for this pair is Water of the Milky Way, yet the line opens 丙午火, with fire where the very next entry has 水 for 丁未. That suggests a slip, though nothing in the text can confirm it. Its image is 月轮, the disk of the moon, with the comment 喜夜及秋，水旺也: it likes night and autumn, when water is at its height.
