Day pillar 18 of 60
辛巳 xin si
Metal stem over Fire branch. The yin metal day master, sitting on the Snake (巳).
Every structural fact about 辛巳 below can be checked against an almanac; only the passage marked conventionally read as is interpretation.
辛 above, 巳 below
The branch controls the stem: Fire restrains Metal. The stem is working against its own footing, which shows up as effort that costs more than it should.
Where 辛巳 sits in the five elements
Wood and Water do not appear anywhere in this pillar.
Metal leads at 48.1%, then fire at 40.7%.
What is buried inside 巳
巳 hides 3 stems. The primary is 丙 (Fire), what restrains the stem; behind it sit 庚 (Metal, the same element as the stem) and 戊 (Earth, what produces the stem).
辛 meeting 巳: the 死 stage
The twelve stages (十二長生): yang stems run forward, yin stems backward.
辛 meets 巳 at the 死 stage — death.
巳 against 亥, with 申
Opposite across the cycle (六沖), and paired with (六合):
Nayin: 白蜡金
Nayin (納音) groups the cycle in pairs, each with an image. This one shares its image with 庚辰: 白蜡金, “metal of white wax.”
How 辛巳 is conventionally read
辛 is finished metal: jewellery, a needle, the edge that has been honed. 巳 is the fire that has just caught, still gathering.
A metal-element day master on a fire footing — one of eight characters, which colours a chart and does not fix the person.
When the next 辛巳 days fall
The sixty-cycle repeats every sixty days, so this pillar returns roughly every two months. The next one is 3 November 2026 (Tuesday). Each is calculated at midday Beijing time; a birth in the hour before midnight can still belong to the previous 辛巳 day, because the day rolls at 23:00 true solar time.

辛 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 |
|---|---|---|---|
| 辛未 | 未 · Goat | Metal on Earth | decline |
| 辛巳 ← | 巳 · Snake | Metal on Fire | death |
| 辛卯 | 卯 · Rabbit | Metal on Wood | severance |
| 辛丑 | 丑 · Ox | Metal on Earth | nurture |
| 辛亥 | 亥 · Pig | Metal on Water | bath |
| 辛酉 | 酉 · Rooster | Metal on Metal | office |
Here the footing is Fire — what restrains the stem. The other five branches this stem sits on are 未 (Earth), 卯 (Wood), 丑 (Earth), 亥 (Water), 酉 (Metal).
