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 Geng Xu day has Geng metal as their Day Master, sitting on the 戌 (earth) branch.

Personality

Geng metal is decisive; the Dog underneath gives loyalty and a strong sense of duty. You keep your word and expect the same, and you are more affected than you admit when someone does not. Principle is your spine, and sometimes your blind spot.

Work and vocation

Law, engineering, security, military, or public service — institutions built on commitments that outlast moods.

Relationships

Faithful and blunt, and inclined to treat warmth as a concession. It is not; warmth is how principle becomes credible.

Health and rhythm

Chest, lungs and dryness. Resentment held quietly tends to settle in the shoulders and the breath.

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