Your Day Master (日主 rìzhǔ) is Wù 戊 — Yang Earth: the mountain — containing, reliable, slow to move and hard to argue with. Wù holds: teams, families, positions, lines that should not be crossed. People instinctively shelter behind a Wù in a storm. The gift is stability that others can build on. The shadow is inertia dressed as principle — holding still when the season says move.

The Wù temperament
In the five-element mechanics, Wù is fed by Fire, expresses itself through Metal, treats Water as its wealth, and answers to Wood as pressure and authority. Those four arrows explain most of what this stem loves and avoids: seasons, people and jobs are experienced as more or less of each.
In charts we read Wù as the load-bearing stem. Where other Day Masters ask “what do I want”, Wù asks “what am I responsible for” — and the answers accumulate, because a mountain never says the valley is full. Under pressure Wù goes quiet and takes more weight; the failure is never dramatic, just a slow settling until one day the person who held everyone discovers nobody thought to hold them. Wood — deadlines, demanding bosses, disruptive change — is what keeps a Wù from fossilising, which is why the most alive Wù charts usually contain the very pressure their owner claims to hate.
In relationships Wù is the terrain itself: constant, sheltering, unhurried. Partners get certainty; what they sometimes miss is expressiveness, since the mountain assumes its presence speaks. Saying the feeling out loud, once a week, is cheap maintenance for a Wù marriage.
Strong Wù, weak Wù
A strong Wù needs Wood — challenge, disruption, someone allowed to dig — or it calcifies into pure immovability. A weak Wù, undermined or overloaded, needs Fire: recognition, warmth, resources that rebuild the slope before more weight is added.

Wù through the four seasons
Season sets the mountain’s baseline. The classical grades are 旺 wàng (Prosperous), 相 xiàng (Supported), 休 xiū (Resting), 囚 qiú (Confined) and 死 sǐ (Dormant) — solar-term seasons, not calendar months.
| Season | Branches | Dates | Wù’s state |
|---|---|---|---|
| Wù born in spring | 寅卯辰 | Feb 4 – May 4 | 死 sǐ — Dormant |
| Wù born in summer | 巳午未 | May 5 – Aug 6 | 相 xiàng — Supported |
| Wù born in autumn | 申酉戌 | Aug 7 – Nov 6 | 休 xiū — Resting |
| Wù born in winter | 亥子丑 | Nov 7 – Feb 3 | 囚 qiú — Confined |
In spring, Wood controls Earth: the weakest baseline, where support and timing matter more than effort. In summer, Fire produces Earth: strong by backing, comfortable, resourced, sometimes over-sheltered. In autumn your element feeds the season’s Metal — energy flows out, a mild drain, the retired-general state. In winter Earth dams the Water it controls — a wealth season, but fighting uphill against the times: effortful, gritty.
One nuance specific to Earth: classical doctrine also gives Earth its own prosperity in the four transitional months 辰未戌丑 (土旺四季 tǔ wàng sì jì), strongest in late summer (未). A Wù born in a Chén, Wèi, Xū or Chǒu month is standing on firmer ground than the season-core state alone suggests — the season pages walk through this.
Career and money
Custodial power suits Wù: operations, infrastructure, property, risk, governance — anywhere the job is to be the thing that does not fail. Water is the wealth element: flowing opportunities dammed and directed by patient containment. Wù wealth is boring on purpose, and compounds.
The Ten Gods for a Wù Day Master
Relative to Wù, every stem in the chart becomes one of the Ten Gods (十神 shíshén). The mapping is fixed; what your chart does with it is the interesting part, covered in the Ten Gods for Wù Earth.
| Stem | Ten God for Wù |
|---|---|
| Jiǎ 甲 (Yang Wood) | Seven Killings 七杀 |
| Yǐ 乙 (Yin Wood) | Direct Officer 正官 |
| Bǐng 丙 (Yang Fire) | Indirect Resource 偏印 |
| Dīng 丁 (Yin Fire) | Direct Resource 正印 |
| Wù 戊 (Yang Earth) | Friend 比肩 |
| Jǐ 己 (Yin Earth) | Rob Wealth 劫财 |
| Gēng 庚 (Yang Metal) | Eating God 食神 |
| Xīn 辛 (Yin Metal) | Hurting Officer 伤官 |
| Rén 壬 (Yang Water) | Indirect Wealth 偏财 |
| Guǐ 癸 (Yin Water) | Direct Wealth 正财 |
Your six Wù day pillars
The Day Master sits on a day branch; together they form the day pillar (日柱 rìzhù), the unit we actually read. As a yang stem, Wù pairs with six branches: Wù Zǐ 戊子, the mountain over the underground spring; Wù Yín 戊寅, the forested mountain; Wù Chén 戊辰, the mountain on deep spring earth; Wù Wǔ 戊午, the mountain with fire in its belly; Wù Shēn 戊申, the mountain veined with ore; and Wù Xū 戊戌, the high dry plateau. Since the day branch is also the spouse palace, these six diverge most in relationship readings — each has its own page.
Wù in 2026 — the Bǐng Wǔ year
2026’s double Fire feeds Earth generously — a resource year: learning, consolidation, foundations poured while the kiln is hot. The risk for a strong Wù is baked-in rigidity (too much Fire hardens clay); keep one channel of Water moving. For a weak Wù this is the rebuilding year the chart has been waiting for.
For how a double-Fire year works in general, read the 2026 Fire Horse guide.

A Day Master is the first sentence of a chart, not the whole paragraph. The season you were born into, the hidden stems beneath your branches, and your current luck pillar decide which version of Wù is on duty this decade. For the whole chart in plain English — with the next twelve months mapped — book a reading, or see the other nine stems in the field guide.
