Kāi

開, open, is the eleventh officer, on the 子 day of the 寅 month. For 協紀辨方書 卷四 this is the point where the count turns over: ten returns to one, and the next round of 建 grows out of it. That is the stated reason for its other names, 生氣, living qi, and 時陽. 卷四 adds that yang is born at this place in the series.

The editors of 1741 call it the most favorable of the twelve, and its suited list is the longest of the twelve in 卷十, stretching from offerings and amnesties to building, wells and planting. Offerings, prayers and grants of rank were missing from the older list, so they supplied them. Six items are avoided all the same: felling, hunting and fishing, which the editors say would harm the new growth, and breaking ground, burial and reburial, which they say are avoided in deference to custom. A closing rule in 卷十 adds that a 開 day is marked neither suited nor avoided for those three unless another avoidance applies. Marriage is left out because the day has no harmony to draw on.

選擇宗鏡 calls it top grade through 青龍, 太隂, 生氣 and 華蓋, with a slight mark against it from 弔客, and 星厯考原 lists it as favorable while doubting that 弔客 belongs. The 青龍 in that list is another item from the spirit named 青龍 on this site. The calculator marks position eleven. Where this list names illness, money or contracts, it reports the 1741 book and is no guidance; ask a doctor or another qualified person about real decisions.
