己巳 ji si

己 above, 巳 below

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

Where 己巳 sits in the five elements

Wood and Water do not appear anywhere in this pillar.

Earth leads at 48.1%, then fire at 40.7%.

What is buried inside 巳

巳 hides 3 stems. The primary is 丙 (Fire), what produces the stem; behind it sit 庚 (Metal, what the stem produces) and 戊 (Earth, the same element as the stem).

己 meeting 巳: the 帝旺 stage

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

己 meets 巳 at the 帝旺 stage — peak.

巳 against 亥, with 申

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

Clashes with

亥 (Pig) — 乙亥

Combines with

申 (Monkey) — 壬申

Nayin: 大林木

Nayin (納音) groups the cycle in pairs, each with an image. This one shares its image with 戊辰: 大林木, “wood of the great forest.”

How 己巳 is conventionally read

己 is cultivated soil: earth that is worked, turned, and made to grow things. 巳 is the fire that has just caught, still gathering.

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

When the next 己巳 days fall

The sixty-cycle repeats every sixty days, so this pillar returns roughly every two months. The next one is 21 December 2026 (Monday). Each is calculated at midday Beijing time; a birth in the hour before midnight can still belong to the previous 己巳 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.

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