ding-you day pillar

Growth arrives in an unexpected place for 丁: its 長生 is at 酉, the Rooster, the very branch where 丙 reaches Death. 三命通會 卷二 states this mirror rule for all the yin stems, and 滴天髓 accepts it while warning readers against holding to it.

Fire over metal is a controlling relation, and 酉 is unusually simple inside. This site's table finds only 辛, which to 丁 is Indirect Wealth, yin metal at matching polarity. 三命通會 divides the month between 庚 for seven days and 辛 for twenty-three, a reminder that these tables vary.

The image from 三命通會 卷一 is the strangest in this stretch of the sixty: 鬼神之灵响, the spirit-like echo of ghosts and gods, which it explains as 火无形者, fire without form. It says this fire likes the four earth branches 辰, 戌, 丑 and 未. Fire at the Foot of the Mountain, the 納音 label, is the one 丙申 also carries.
