丁 · Yin Fire

dīng · 丁火 · the fourth heavenly stem

丁 dīng is the fourth of the ten heavenly stems in BaZi: Yin Fire, the stem of summer and the South. The heavenly stems are the upper half of each pillar in a chart, and the stem of the day pillar is the Day Master, the person the chart is about. 丁 combines with 壬 into Wood and clashes with 癸.

Firelight: the candle, the lamp, the forge. Small but focused, and brightest in the dark. People with a 丁 Day Master tend to be attentive, warm and devoted to a few things.

Readings are interpretations. Different traditions describe the same stem differently, and what a stem means in a chart depends on the company it keeps: the month it sits in, the branch beneath it and the balance of the other elements.

Combination and clash are the standard stem relations the engine uses. They describe the pair, not a person.

Where you meet it

• As a Day Master, the stem of your day pillar: the person the chart is about.
• In any other pillar, where it is read through the Ten Gods relative to your Day Master.
• Hidden inside a branch: 丁 hides in 午 Horse, 未 Goat and 戌 Dog.

In the app, tapping any 丁 in your chart opens this entry, with one line on what it is doing in your chart. That line needs your pillars, so it is not on this page.
