Day pillar 30 of 60
癸巳 gui si
Water stem over Fire branch. The yin water day master, sitting on the Snake (巳).
Every structural fact about 癸巳 below can be checked against an almanac; only the passage marked conventionally read as is interpretation.
癸 above, 巳 below
The stem controls the branch: Water restrains Fire. The pillar is internally under tension, and that tension is structural, not a mood.
Where 癸巳 sits in the five elements
Wood does not appear anywhere in this pillar.
Fire leads at 40.7%, then water at 37.0%.
What is buried inside 巳
巳 hides 3 stems. The primary is 丙 (Fire), what the stem restrains; behind it sit 庚 (Metal, what produces the stem) and 戊 (Earth, what restrains the stem).
癸 meeting 巳: the 胎 stage
The twelve stages (十二長生): yang stems run forward, yin stems backward.
癸 meets 巳 at the 胎 stage — conception.
巳 against 亥, with 申
Opposite across the cycle (六沖), and paired with (六合):
Nayin: 长流水
Nayin (納音) groups the cycle in pairs, each with an image. This one shares its image with 壬辰: 长流水, “water of the long stream.”
How 癸巳 is conventionally read
癸 is water that arrives quietly: rain, mist, groundwater. 巳 is the fire that has just caught, still gathering.
A water-element day master on a fire footing — one of eight characters, which colours a chart and does not fix the person.
When the next 癸巳 days fall
The sixty-cycle repeats every sixty days, so this pillar returns roughly every two months. The next one is 15 November 2026 (Sunday). Each is calculated at midday Beijing time; a birth in the hour before midnight can still belong to the previous 癸巳 day, because the day rolls at 23:00 true solar time.

Showing up to eight of the 6 occurrences in the next twelve months, from 2026-10-31.
癸 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 |
|---|---|---|---|
| 癸酉 | 酉 · Rooster | Water on Metal | illness |
| 癸未 | 未 · Goat | Water on Earth | tomb |
| 癸巳 ← | 巳 · Snake | Water on Fire | conception |
| 癸卯 | 卯 · Rabbit | Water on Wood | birth |
| 癸丑 | 丑 · Ox | Water on Earth | cap and girdle |
| 癸亥 | 亥 · Pig | Water on Water | peak |
Here the footing is Fire — what the stem restrains. The other five branches this stem sits on are 酉 (Metal), 未 (Earth), 卯 (Wood), 丑 (Earth), 亥 (Water).
