乙亥 yi hai

乙 above, 亥 below

The branch generates the stem: Water produces Wood. This is the more comfortable arrangement of the two — the ground under the stem is feeding it rather than draining it.

Where 乙亥 sits in the five elements

Fire, Earth and Metal do not appear anywhere in this pillar.

Wood leads at 54.2%, then water at 45.8%.

What is buried inside 亥

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

乙 meeting 亥: the 死 stage

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

乙 meets 亥 at the 死 stage — death.

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: 山头火

Nayin (納音) groups the cycle in pairs, each with an image. This one shares its image with 甲戌: 山头火, “fire on the mountain top.”

How 乙亥 is conventionally read

乙 is the same wood as 甲, but as a vine that bends and keeps climbing. 亥 is the water that gathers at the end and starts the next turn.

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

When the next 乙亥 days fall

The sixty-cycle repeats every sixty days, so this pillar returns roughly every two months. The next one is 27 December 2026 (Sunday). Each is calculated at midday Beijing time; a birth in the hour before midnight can still belong to the previous 乙亥 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.

乙 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 produces the stem. The other five branches this stem sits on are 丑 (Earth), 酉 (Metal), 未 (Earth), 巳 (Fire), 卯 (Wood).
