Day pillar 3 of 60

丙寅 bing yin

Fire stem over Wood branch. The yang fire day master, sitting on the Tiger (寅).

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

丙 above, 寅 below

丙 Heavenly stem Fire 火 · yang
寅 Earthly branch Wood 木 · Tiger

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 丙寅 sits in the five elements

Metal and Water do not appear anywhere in this pillar.

Fire48.1%
Wood40.7%
Earth11.1%

Fire leads at 48.1%, then wood at 40.7%.

What is buried inside 寅

甲Woodprimary
丙Firemiddle
戊Earthresidual

寅 hides 3 stems. The primary is 甲 (Wood), what produces the stem; behind it sit 丙 (Fire, the same element as the stem) and 戊 (Earth, what the stem produces).

丙 meeting 寅: the 長生 stage

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

長生
birth the first emergence — capacity is present but nothing has been proved yet

丙 meets 寅 at the 長生 stage — birth.

寅 against 申, with 亥

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

Clashes with
申 (Monkey) — 壬申
Combines with
亥 (Pig) — 乙亥

Nayin: 炉中火

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

How 丙寅 is conventionally read

丙 is the sun itself: visible, outward, impossible to keep indoors. 寅 is the first month, the push that begins the year.

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 丙寅 days fall

The sixty-cycle repeats every sixty days, so this pillar returns roughly every two months. The next one is 18 December 2026 (Friday). Each is calculated at midday Beijing time; a birth in the hour before midnight can still belong to the previous 丙寅 day, because the day rolls at 23:00 true solar time.

丙 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:

丙子子 · RatFire on Waterconception
丙戌戌 · DogFire on Earthtomb
丙申申 · MonkeyFire on Metalillness
丙午午 · HorseFire on Firepeak
丙辰辰 · DragonFire on Earthcap and girdle

Here the footing is Wood — what produces the stem. The other five branches this stem sits on are 子 (Water), 戌 (Earth), 申 (Metal), 午 (Fire), 辰 (Earth).
