Ding Mao·丁卯·Jeongmyo
Written by DK
The Ding Mao day pillar, 丁卯 in hanja and 정묘 (Jeongmyo) in Korean Saju, is a yin Fire day master on a Wood branch. Of the 24,112 丁 charts this site has measured, 4,015 fall on a 丁卯 day. Those read as strong in 39.6 per cent of cases, weak in 38.3 and balanced in 22.0. Taking every 丁 day together the split is 31.0 per cent strong, 49.4 weak and 19.5 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 卯 holds, and what each of those stems is to a 丁 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 丁 |
|---|---|---|---|
| 乙 Yin Wood | 正氣 primary | 20 of 30 | 偏印 Indirect Resource |
| 甲 Yang Wood | 餘氣 residual | 10 of 30 | 正印 Direct Resource |
In the twelve-stage cycle a 丁 day master on 卯 sits at 病 Illness.
Personality性
Ding is Yin Fire — candle or lamp flame rather than the blaze of the sun — and in this pillar it sits directly atop 卯 (Mao), a branch of pure Wood. Wood generates Fire, so the Day Master (the stem representing the self) is continuously fed by the branch beneath it; the flame is never starved of fuel. But the twelve-stage life-cycle position here is 病 Illness — a waning stage, past the branch's own peak — so the fuel supply does not translate into robustness. This is a person whose identity is well-nourished but not vigorous: reflective, easily tired, prone to running on reserves rather than raw stamina. The hidden stems (지장간, the qi buried inside the branch) confirm the picture. Both are Wood, and both read as Resource toward the Day Master: 乙 Yi Wood as primary qi at 20 of 30 days gives 偏印 Indirect Resource, the dominant Ten God of the whole pillar; 甲 Jia Wood as residual qi at 10 days gives 正印 Direct Resource. No Officer, no Wealth, no Output, no Companion appears in the branch at all — this is a pillar built entirely out of the Resource domain. That produces a mind oriented toward absorbing rather than asserting: study, intuition, private conviction, an inward relationship to knowledge rather than a competitive or acquisitive one. Because Indirect Resource outweighs Direct Resource two to one, the learning style leans unconventional — self-taught insight, philosophy, or esoteric interest even inside credentialed work — over textbook orthodoxy.
Career職
With Resource dominant and no Officer to impose external structure, this Day Master does its best work where knowledge, guidance, or care is the product rather than authority or output for its own sake — teaching, research, counseling, medicine, writing, or fields touching religion and the esoteric, all traditional homes for 偏印 Indirect Resource. The Illness stage argues against paths built on sustained physical exertion or constant competitive exposure; the flame does better with institutional or mentor support that lets it recover between efforts than with roles demanding uninterrupted output.
Wealth財
Neither 正財 Direct Wealth nor 偏財 Indirect Wealth appears among the hidden stems — this pillar carries no innate Wealth god. Money is not the structural center of this identity the way it is for pillars with Wealth rooted in the branch; income tends to arrive as a byproduct of expertise or reputation rather than from active pursuit of it. The Resource-heavy branch inclines toward valuing security, credentials, and knowledge over commercial risk-taking, and toward under-attending to opportunity when it looks purely transactional.
Love & Compatibility緣
Fire here is the low, steady kind — warmth sustained rather than declared — but the Illness stage means the reserves behind that warmth are limited, and depletion shows as withdrawal rather than conflict. Because the branch is pure Resource with no Wealth or Officer star (the stems that classically anchor the spouse in a chart), attraction and commitment are not written into this pillar's own structure; they arrive through other placements. What this temperament brings is loyalty, empathy, and a need for a partner who feels like nourishment — someone to think alongside — and what it struggles with is stating needs directly, preferring retreat and quiet endurance over confrontation.
Best & Worst Pairings合
The best matches all come from 六合 Six Harmony with 戌 (Xu), which combines with 卯 to transform into Fire — directly feeding this Day Master's own element rather than its Resource. 壬戌 Ren Xu brings 正官 Direct Officer, supplying the structure this pillar's branch otherwise lacks; 庚戌 Geng Xu brings 正財 Direct Wealth, supplying the material grounding this pillar's branch otherwise lacks; 甲戌 Jia Xu brings 正印 Direct Resource, doubling down on the pillar's own Resource nature with a steadier, more orthodox version of it. All three sit at the 養 Nurture stage, a gestational, supportive position that suits a Day Master needing steady rather than intense reinforcement. The worst matches all come from 沖 Clash with 酉 (You), which strikes Mao directly — and since Mao is this Day Master's sole resource and root, the clash cuts the very supply line that keeps the flame lit. 癸酉 Gui You is worst of all, adding 七殺 Seven Killings, an unmediated pressure with none of the fairness an Officer would bring; 辛酉 Xin You brings 偏財 Indirect Wealth and 乙酉 Yi You brings 偏印 Indirect Resource, but in both cases the Metal of You still opposes and severs Wood before any benefit of the stem can register.
