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
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.
Wood leads at 52.4%, then fire at 47.6%.
What is buried inside 卯
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.
丁 meets 卯 at the 病 stage — illness.
卯 against 酉, with 戌
Opposite across the cycle (六沖), and paired with (六合):
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.
| Date | Weekday | Year / month / day pillar |
|---|---|---|
| 2026-12-19 | Saturday | 丙午 庚子 丁卯 |

Showing up to eight of the 6 occurrences in the next twelve months, from 2026-10-31.
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:
| Pillar | Branch | Footing | Stage |
|---|---|---|---|
| 丁卯 ← | 卯 · Rabbit | Fire on Wood | illness |
| 丁丑 | 丑 · Ox | Fire on Earth | tomb |
| 丁亥 | 亥 · Pig | Fire on Water | conception |
| 丁酉 | 酉 · Rooster | Fire on Metal | birth |
| 丁未 | 未 · Goat | Fire on Earth | cap and girdle |
| 丁巳 | 巳 · Snake | Fire on Fire | peak |
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).
