辛亥 xin hai

辛 above, 亥 below

The stem generates the branch: Metal produces Water. The upper half of the pillar feeds the lower half, so the visible stem is spending itself on what it sits above.

Where 辛亥 sits in the five elements

Fire and Earth do not appear anywhere in this pillar.

Water leads at 45.8%, then metal at 41.7%.

What is buried inside 亥

亥 hides 2 stems. The primary is 壬 (Water), what the stem produces; behind it sit 甲 (Wood, what the stem restrains).

辛 meeting 亥: the 沐浴 stage

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

辛 meets 亥 at the 沐浴 stage — bath.

亥 against 巳, with 寅

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

Clashes with

巳 (Snake) — 己巳

Combines with

寅 (Tiger) — 丙寅

Nayin: 钗钏金

Nayin (納音) groups the cycle in pairs, each with an image. This one shares its image with 庚戌: 钗钏金, “gold of the hairpin.”

How 辛亥 is conventionally read

辛 is finished metal: jewellery, a needle, the edge that has been honed. 亥 is the water that gathers at the end and starts the next turn.

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

When the next 辛亥 days fall

The sixty-cycle repeats every sixty days, so this pillar returns roughly every two months. The next one is 3 December 2026 (Thursday). Each is calculated at midday Beijing time; a birth in the hour before midnight can still belong to the previous 辛亥 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.

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:

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