Yang Wood Dragon (甲辰) 甲辰

In the 60 Jiazi sexagenary cycle, 甲辰 (Yang Wood Dragon) sits at position 41 of 60. It pairs the Heavenly Stem 甲 — the Yang expression of Wood, covered in depth in the Yang Wood Day Master entry — with the Earthly Branch 辰 (the Dragon), whose primary element is Earth and which secondarily holds the hidden stems 戊 (Yang Earth), 乙 (Yin Wood), 癸 (Yin Water).

The classical character of any Jiazi comes from two structural questions: what relationship the branch element has to the stem element above it, and whether the stem has a “root” in any of the branch’s hidden stems. Both are deterministic and apply consistently wherever this Jiazi appears in a chart — Year, Month, Day, or Hour pillar — though the practical implication shifts with position.

The stem controls the branch’s element. From 甲’s perspective, 辰 represents wealth (財) — resources the stem can act on if it has the strength to do so. 甲辰 favours acquisition and material themes when the stem is sufficiently rooted; without rooting, the stem tries to control wealth it cannot actually hold.

甲 is rooted in this Jiazi: at least one hidden stem in 辰 carries the same Wood element, giving the visible stem genuine strength rather than sitting on foreign ground. A rooted stem behaves more reliably in interpretation — its qualities are anchored, not floating.

辰 carries 戊 (Yang Earth), 乙 (Yin Wood), 癸 (Yin Water) as hidden stems. In BaZi these are latent influences: they only surface when the rest of the chart triggers them — through combinations involving 辰, through clashes that crack open the branch, or through transformations during specific Luck Pillars.

From 甲’s perspective, the hidden stems represent the following Ten God relationships: 戊 as 偏財 Indirect Wealth; 乙 as 劫財 Rob Wealth; 癸 as 正印 Direct Resource. These determine what kinds of opportunity, pressure, or support emerge from 辰 when it is activated.

In the classical Nayin (納音) system, every pair of consecutive Jiazis maps to one of 30 named “sounding elements” — an alternative elemental classification used alongside the standard Five Phases. 甲辰 is classified as 覆灯火 (Fù dēng huǒ, “Lamp Fire”), with an underlying element of Fire.

Nayin is read as a poetic, descriptive layer rather than a structural one: the imagery of the name (“Lamp Fire”) implies how the Jiazi’s elemental quality manifests in practice. 甲辰 shares its Nayin with one other Jiazi: 乙巳 (Yin Wood Snake). Together, this pair forms the 覆灯火 Nayin set.

Every Earthly Branch has exactly one combination partner (六合) and one clash partner (六沖). When a chart contains both members of a pair, the relationship transforms or destabilises that pillar. 辰’s pairings:

In BaZi, the twelve Earthly Branches form four 3-Harmony groups (三合): trios that, when all three branches appear together in a chart, combine to produce a single elemental phase. 辰 belongs to the 申+子+辰 group, which combines into Water. The other two branches in this group are 申 and 子.

When 辰 appears with both partner branches, the resulting elemental transformation can dominate the chart’s reading. Even a partial harmony (two of the three branches) creates a noticeable pull toward Water. Other Jiazis carrying the partner branches: 甲子, 壬申, 丙子, 甲申, 戊子, 丙申, 庚子, 戊申, 壬子, 庚申.

The four direction sets (三會) group the twelve Earthly Branches by season and cardinal direction: 辰 belongs to 寅+卯+辰 — the Spring group, associated with East and the Wood element.

Direction sets carry a “seasonal weight” that complements the 3-Harmony grouping. Where 3-Harmony combines distant branches into one element, direction sets combine three sequential branches representing the early/middle/late phase of one season. Other Jiazis sharing this direction set: 丙寅, 丁卯, 戊寅, 己卯, 庚寅, 辛卯, 壬寅, 癸卯, 甲寅, 乙卯.

When 甲辰 sits at the Year Pillar, its stem (甲) takes on a different Ten God meaning depending on the chart owner’s Day Master. Each row below is computed deterministically from the elemental and polarity relationship.

The 60 Jiazi cycle repeats every 60 years, so 甲辰 appears at fixed intervals. Within the 1900–2030 reference range, the years carrying 甲辰 are below. Each links to a full reference page for that calendar year.
