Day pillar 4 of 60

丁卯 ding mao

Fire stem over Wood branch. The yin fire day master, sitting on the Rabbit (卯).

Every structural fact about 丁卯 below can be checked against an almanac; only the passage marked conventionally read as is interpretation.

丁 above, 卯 below

丁 Heavenly stem Fire 火 · yin
卯 Earthly branch Wood 木 · Rabbit

The branch generates the stem: Wood produces Fire. This is the more comfortable arrangement of the two — the ground under the stem is feeding it rather than draining it.

Where 丁卯 sits in the five elements

Earth, Metal and Water do not appear anywhere in this pillar.

Wood52.4%
Fire47.6%

Wood leads at 52.4%, then fire at 47.6%.

What is buried inside 卯

乙Woodprimary

卯 hides a single stem, 乙 (Wood) — what produces the stem.

丁 meeting 卯: the 病 stage

The twelve stages (十二長生): yang stems run forward, yin stems backward.

病
illness weakened, needing support it cannot fully replace

丁 meets 卯 at the 病 stage — illness.

卯 against 酉, with 戌

Opposite across the cycle (六沖), and paired with (六合):

Clashes with
酉 (Rooster) — 癸酉
Combines with
戌 (Dog) — 甲戌

Nayin: 炉中火

Nayin (納音) groups the cycle in pairs, each with an image. This one shares its image with 丙寅: 炉中火, “fire in the furnace.”

How 丁卯 is conventionally read

丁 is a flame held in the hand: smaller than 丙, more deliberate, warmer at close range. 卯 is early spring at its purest, entirely growth.

A fire-element day master on a wood footing — one of eight characters, which colours a chart and does not fix the person.

When the next 丁卯 days fall

The sixty-cycle repeats every sixty days, so this pillar returns roughly every two months. The next one is 19 December 2026 (Saturday). Each is calculated at midday Beijing time; a birth in the hour before midnight can still belong to the previous 丁卯 day, because the day rolls at 23:00 true solar time.

丁 on six different footings

Six pillars carry this stem. It is the same day master every time, so everything that differs below is caused by the branch underneath it:

PillarBranchFootingStage
丁卯 ←卯 · RabbitFire on Woodillness
丁丑丑 · OxFire on Earthtomb
丁亥亥 · PigFire on Waterconception
丁酉酉 · RoosterFire on Metalbirth
丁未未 · GoatFire on Earthcap and girdle
丁巳巳 · SnakeFire on Firepeak

Here the footing is Wood — what produces the stem. The other five branches this stem sits on are 丑 (Earth), 亥 (Water), 酉 (Metal), 未 (Earth), 巳 (Fire).
