Day Master

己 Ji: the Yin Earth Day Master

Nurturing, practical, and absorbing, like soil that helps things grow.

By the Daoly team · Updated November 2026

What Yin Earth is like in BaZi

己 is imagined as fertile field or garden soil. Ji charts are often described as caring and practical, good at creating the conditions in which others can do well.

Common strengths

  • Care and practicality
  • Attention to detail
  • Helping others grow

Common blind spots

  • Absorbing other people's problems
  • Worrying over details
  • Putting your own needs last

What this Day Master tends to need

Readings often consider Fire for warmth and Water in moderation, since soil can dry out or wash away.

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

Ji combines with 甲 Jia (Yang Wood). Its output is Metal, its wealth is Water, its pressure comes from Wood, and its support comes from Fire.

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