己亥

Ji Hai (己亥) — Yin Earth on the Pig

A soft field drinking in a slow river.

Heavenly stem: 己 · Ji · Yin Earth
Earthly branch: 亥 · Hai · Pig
Na Yin: Wood on the Plain
Hidden stems: Ren, Jia
Hidden gods: Direct Wealth, Direct Officer
Branch element: Water

Rich soil meeting generous water, fertile and at ease.

In BaZi, the day pillar is the pillar of the self. Its heavenly stem is your Day Master — the reference point for every other character in the chart. A person born on a Ji Hai day has Ji earth as their Day Master, sitting on the 亥 (water) branch.

Personality

Ji earth is nurturing; the Pig underneath adds generosity and ease. You make people comfortable almost immediately, and you take on more than you announce. The result is a life that looks calm from the outside and feels busier than it appears.

Work and vocation

Hospitality, education, healthcare, community work, or HR — places where the atmosphere is part of what people came for.

Relationships

Warm and accommodating, and prone to giving first and negotiating later. Let others give to you; it is not a debt to repay.

Health and rhythm

Digestion and fluid balance. Comfort eating is usually your signal that a boundary has been quietly crossed.

Upcoming 己亥 days

The sexagenary day cycle repeats every sixty days. These are the next dates that fall on Ji Hai.
