Yi You·乙酉·Eulyu
Written by DK
The Yi You day pillar, 乙酉 in hanja and 을유 (Eulyu) in Korean Saju, is a yin Wood day master on a Metal branch. Of the 24,101 乙 charts this site has measured, 4,015 fall on a 乙酉 day. Those read as strong in 17.7 per cent of cases, weak in 67.1 and balanced in 15.3. Taking every 乙 day together the split is 31.9 per cent strong, 47.9 weak and 20.2 balanced.
The figures come from running this site’s engine over every day of the stem from 1950 to 2009, with a birth in Seoul every two hours from two in the morning to ten at night. Midnight is left out: once Seoul’s clock is corrected for its longitude, a midnight birth falls on the day before, which carries a different stem.
Structure藏干
What the branch 酉 holds, and what each of those stems is to a 乙 day master. The day counts are the classical weights within a thirty-day month, main stem first.
| Hidden stem | Qi | Days of 30 | Ten God to 乙 |
|---|---|---|---|
| 辛 Yin Metal | 正氣 primary | 20 of 30 | 七殺 Seven Killings |
| 庚 Yang Metal | 餘氣 residual | 10 of 30 | 正官 Direct Officer |
In the twelve-stage cycle a 乙 day master on 酉 sits at 絕 Extinction.
Personality性
Yi Wood is the pliant plant — vine, reed, flower stem — never the standing timber of Jia Wood, and it survives by bending rather than resisting. Placed on 酉 You, a branch that is solid Metal, the Day Master finds nothing to lean on: both hidden stems are Metal, and both express as authority gods that check Wood rather than feed it. 辛 Xin, Yin Metal, holds the primary qi at 20 of 30 days and reads as 七殺 Seven Killings — command without negotiation, pressure applied as a test rather than a promotion. 庚 Geng, Yang Metal, holds the residual 10 days as 正官 Direct Officer — the milder, rule-bound form of the same control. There is no Resource, Output, Wealth, or Companion god hidden in this branch at all; the entire structure it offers the Day Master is pressure, restating in the hidden stems the same relation the pillar states outright — Wood controlled by Metal. The seated life-cycle stage, 絕 Extinction, is the lowest point of the twelve-stage cycle, the moment before any new form exists. For a Day Master this soft, sitting at Extinction under concentrated Metal control describes someone who meets authority not by confronting it but by dissolving into whatever shape it demands, then quietly reconstituting afterward. The result is a person who reads a room's hierarchy instantly, complies strategically rather than resentfully, and is more at ease under a hard rule than in an unstructured negotiation — because the Seven Killings pressure outweighs the Direct Officer's fairness nearly two to one.
Career職
With both hidden stems expressing as authority gods and nothing else present, this pillar suits work defined by hierarchy rather than self-direction: regulated professions, civil service, law, examination-based credentialing, enforcement, or institutions with strict chains of command. The Seven Killings weight favors environments with real stakes and testing — crisis response, competitive selection, disciplinary or oversight roles — where performance under someone else's terms is the job itself. The smaller Direct Officer current draws toward the more legitimate end of that same field: established organizations with codified rules rather than arbitrary bosses. Because no Wealth or Output god appears in the branch, entrepreneurial or freelance paths receive no support here; standing, not enterprise, is the natural reward structure. The Extinction stage adds a practical caveat — this configuration cannot sustain Rooster-grade demand indefinitely without periodic withdrawal, so careers built around this pillar tend to run in cycles of intense service followed by necessary reinvention.
Wealth財
Neither 正財 Direct Wealth nor 偏財 Indirect Wealth appears among the hidden stems — the branch is given over entirely to authority gods. This is not a chart built around acquiring or managing money directly; income arrives as a consequence of position, title, or compliance rather than commerce or investment. Money handled this way tends to be treated cautiously and tied to salary or institutional standing rather than risk-taking, since nothing in the pillar itself models negotiation, enterprise, or resource-building. Wealth accumulation, where it happens, depends on other pillars in the full chart; this day pillar alone supplies service and rank, not capital.
Love & Compatibility緣
The Yin Wood nature brings real adaptability to a relationship — a willingness to bend, accommodate, and absorb friction rather than force a confrontation. But a temperament shaped by Seven Killings and Direct Officer, sitting at Extinction, can mistake being controlled for being cared for, accepting testing or dominance from a partner the way it has learned to accept pressure from authority elsewhere. Asserting personal needs directly is the harder move, since Extinction favors dissolving the self rather than staking a claim for it. What this pillar brings well is loyalty under structure and a low need for confrontation; what it struggles with is naming its own terms before resentment builds.
Best & Worst Pairings合
The three strongest matches — 壬辰 Ren Chen, 庚辰 Geng Chen, and 戊辰 Wu Chen — all sit on 辰 Chen, which forms a 六合 Six Harmony with 酉 You that transforms to Metal. This reinforces the branch's native Metal leaning but through cooperative union rather than raw domination, and each pairing supplies exactly what the day pillar's branch lacks on its own: Ren Chen brings 正印 Direct Resource (support and nurture where none existed), Geng Chen brings a second, orderly 正官 Direct Officer (structure without the harshness of Seven Killings), and Wu Chen brings 正財 Direct Wealth (a steady resource the day pillar cannot generate for itself). All three arrive at the 冠帶 Guan Dai stage, a young-adult vigor that steadies rather than overwhelms. The three weakest matches — 辛卯 Xin Mao, 癸卯 Gui Mao, and 己卯 Ji Mao — all sit on 卯 Mao, which stands in direct 沖 Clash with 酉 You, and each arrives at 臨官 Linguan, a stage of full vigor that makes the clash hit at full strength. Xin Mao is the harshest of the three, doubling the day pillar's own 七殺 Seven Killings through the clash itself; Gui Mao and Ji Mao clash while also introducing an unrooted 偏印 Indirect Resource or 偏財 Indirect Wealth, unable to stabilize a relationship whose foundation is already being pulled apart.
