jia-xu day pillar

甲 rises over 戌, and since wood controls earth the stem has the ruling part in this pair. The count here gives Nurture, the seat just before 甲 starts over at Growth in 亥. 三命通會 names this phase 成形, to take form in the ground the way a child takes form in the womb.

Three stems sit inside 戌: 戊 as Indirect Wealth, 辛 as Direct Officer, 丁 as Hurting Officer. That third name states only that wood gives rise to this fire at opposite polarity, and its reputation is larger than its arithmetic. 三命通會 swaps 丁 for 丙 and calls 戌 the store of 丙 fire, which from 甲 would be Eating God.

山頭火, Fire on the Mountaintop, goes with 乙亥. 三命通會 卷一 treats 甲戌 as 火所宿处, the place where fire lodges for the night, and says 喜春及夏, pleased by spring and summer. Among the entry's labels is 华盖, literally canopy, and 卷二 names it among the points that count as happy when a luck period reaches them.
