Day pillar 17 of 60

庚辰 geng chen

Metal stem over Earth branch. The yang metal day master, sitting on the Dragon (辰).

Every structural fact about 庚辰 below can be checked against an almanac; only the passage marked conventionally read as is interpretation.

庚 above, 辰 below

庚 Heavenly stem Metal 金 · yang
辰 Earthly branch Earth 土 · Dragon

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

Where 庚辰 sits in the five elements

Fire does not appear anywhere in this pillar.

Earth40.7%
Metal37.0%
Wood11.1%
Water11.1%

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

What is buried inside 辰

戊Earthprimary
乙Woodmiddle
癸Waterresidual

辰 hides 3 stems. The primary is 戊 (Earth), what produces the stem; behind it sit 乙 (Wood, what the stem restrains) and 癸 (Water, what the stem produces).

庚 meeting 辰: the 養 stage

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

養
nurture nurture — being prepared, not yet deployed

庚 meets 辰 at the 養 stage — nurture.

辰 against 戌, with 酉

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

Clashes with
戌 (Dog) — 甲戌
Combines with
酉 (Rooster) — 癸酉

Nayin: 白蜡金

Nayin (納音) groups the cycle in pairs, each with an image. This one shares its image with 辛巳: 白蜡金, “metal of white wax.”

How 庚辰 is conventionally read

庚 is unworked metal: the blade before it is polished. 辰 is damp earth that holds water and receives what falls.

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

When the next 庚辰 days fall

The sixty-cycle repeats every sixty days, so this pillar returns roughly every two months. The next one is 2 November 2026 (Monday). Each is calculated at midday Beijing time; a birth in the hour before midnight can still belong to the previous 庚辰 day, because the day rolls at 23:00 true solar time.

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:

庚寅寅 · TigerMetal on Woodseverance
庚子子 · RatMetal on Waterdeath

Here the footing is Earth — what produces the stem. The other five branches this stem sits on are 午 (Fire), 寅 (Wood), 子 (Water), 戌 (Earth), 申 (Metal).
