Day Master

癸 Gui: the Yin Water Day Master

Intuitive, gentle, and penetrating, like rain or mist.

By the Daoly team · Updated November 2026

What Yin Water is like in BaZi

癸 is imagined as rain, dew, or mist. Gui charts are often described as sensitive and imaginative, with a quiet way of reaching places that force cannot.

Common strengths

  • Intuition
  • Empathy
  • Subtle influence

Common blind spots

  • Absorbing the mood of a room
  • Indirect communication
  • Losing shape without structure

What this Day Master tends to need

Readings often consider Metal as a source and Fire for warmth, particularly in winter charts.

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

Gui combines with 戊 Wu (Yang Earth). Its output is Wood, its wealth is Fire, its pressure comes from Earth, and its support comes from Metal.

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