庚寅 geng yin

庚 above, 寅 below

The stem controls the branch: Metal restrains Wood. The pillar is internally under tension, and that tension is structural, not a mood.

Where 庚寅 sits in the five elements

Water does not appear anywhere in this pillar.

Wood leads at 40.7%, then metal at 37.0%.

What is buried inside 寅

寅 hides 3 stems. The primary is 甲 (Wood), what the stem restrains; behind it sit 丙 (Fire, what restrains the stem) and 戊 (Earth, what produces the stem).

庚 meeting 寅: the 絕 stage

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

庚 meets 寅 at the 絕 stage — severance.

寅 against 申, with 亥

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

Clashes with

申 (Monkey) — 壬申

Combines with

亥 (Pig) — 乙亥

Nayin: 松柏木

Nayin (納音) groups the cycle in pairs, each with an image. This one shares its image with 辛卯: 松柏木, “wood of pine and cypress.”

How 庚寅 is conventionally read

庚 is unworked metal: the blade before it is polished. 寅 is the first month, the push that begins the year.

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

When the next 庚寅 days fall

The sixty-cycle repeats every sixty days, so this pillar returns roughly every two months. The next one is 12 November 2026 (Thursday). Each is calculated at midday Beijing time; a birth in the hour before midnight can still belong to the previous 庚寅 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.

庚 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 Wood — what the stem restrains. The other five branches this stem sits on are 午 (Fire), 辰 (Earth), 子 (Water), 戌 (Earth), 申 (Metal).
