What it is (and is not)

How it is identified
丙 Bing · Yang Fire — year stem
Read against the Day Master, Fire is the element that controls Metal (火克金). That relation is vocabulary for describing structure, not a good or bad sign.
午 Wu · Fire — year branch
The popular Chinese zodiac animal comes from this one character (here, the Horse). That is why a zodiac animal and a Day Master are different things: one is the year branch, the other is the day stem.
己 Ji · Yin Earth — month stem
Earth is the element that produces Metal (土生金) in the five-element cycle.
亥 Hai · Water — month branch
BaZi months follow the 24 solar terms, not calendar months. This sample date falls after Lidong (Start of Winter), so the month branch is Hai. Metal produces Water (金生水).
庚 Geng · Yang Metal — the Day Master
The stem, or top character, of the day pillar. In this sample chart Geng Metal is the reference point: every other character is read by how its element relates to Metal. It names the centre of the chart. It is not a personality description and not a forecast.
寅 Yin · Wood — day branch
It sits under the Day Master in the same pillar, but it is not the Day Master: the Day Master is always the stem, never the branch. Metal is the element that controls Wood (金克木).
辛 Xin · Yin Metal — hour stem
The same element as the Day Master, with the other polarity. The hour stem is worked out from the day stem, which is why an unknown birth hour leaves a three-pillar chart instead of an invented hour.
巳 Si · Fire — hour branch
The two-hour window 09:00–11:00. In a written reading the clock time is first corrected to local solar time for the birth place, which can move a time near a boundary into the next window.
Step 1 · Write the four pillars
A birth date and time become four stem-and-branch pairs — eight characters. The year starts at Lichun (Start of Spring) and months change at solar terms, so the calendar date alone is not enough near a boundary.
Step 2 · Find the day pillar
Days run through an unbroken 60-day cycle of stem-and-branch pairs, so the day pillar does not depend on the month or the year. This sample day is 庚寅 Geng Yin.
Step 3 · Take its stem
Here the Day Master is 庚 Geng, Yang Metal — one of ten possible stems. Nothing else in the chart is called the Day Master.
Step 4 · Read the other seven against it
Produces, controls, same element: this is the “ten gods” language. It describes the structure of a chart. It does not predict events or say whether a chart is good or bad.
