Last of the twelve, 閉 means close and falls on the 丑 day of the 寅 month. 協紀辨方書 卷四 argues that new growth left unsealed could not live, so the series ends in a shutting, and from that shutting the next 建 becomes possible. 淮南子, quoted there, says it governs 太隂. 卷四 gives one alternate name, 血支.

卷十 says plainly that the day is in itself no bad one, and it reads the list as a drawing in before the next round. Two works suit it: building dikes, and patching walls and holes. Appointments, marriage arrangements, moving, eye treatment, palace building and markets are named for avoidance, and as 血支 it carries needling as a single further item. The editors added military campaigns by analogy with travel to a post.

選擇宗鏡 ties it to 病符 and rates it bad, and 星厯考原 sets it among the unfavorable six, where the rhyme says 閉 and 破 do not fit. The 協紀 editors thus stand apart from both of these books. Modern almanacs print further day lists that this site does not show. After 閉 the calculator returns to 建, unless a 節 falls that day and 閉 repeats. 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.
