Day Master

丁 Ding: the Yin Fire Day Master

Focused, intimate, and illuminating, like a flame in a dark room.

By the Daoly team · Updated November 2026

What Yin Fire is like in BaZi

丁 is imagined as a candle, lamp, or forge fire. Ding charts are often described as thoughtful and focused, giving concentrated light to a few things rather than brightness to everything.

Common strengths

  • Depth of attention
  • Insight
  • Quiet warmth

Common blind spots

  • Inner restlessness
  • Sensitivity to atmosphere
  • Overthinking small flickers

What this Day Master tends to need

Readings often value Wood as steady fuel, and consider how much Metal and Water the flame can sustain.

A Day Master's needs depend on season and on the rest of the chart, so two people with the same Day Master can need different things.

Key relationships

Ding combines with 壬 Ren (Yang Water). Its output is Earth, its wealth is Metal, its pressure comes from Water, and its support comes from Wood.

See how these relationships become roles in the Ten Gods guide.
