Hard metal meeting fresh growth, decisive and impatient.

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 Yin day has Geng metal as their Day Master, sitting on the 寅 (wood) branch.

Personality

Geng metal is blunt and principled; the Tiger adds courage and drive. You move first and refine later, and you respect people who can take a direct answer.

Work and vocation

Founding, engineering, military, surgery, construction — action-oriented roles.

Relationships

Protective and honest. Deliver the truth with a little more warmth.

Health and rhythm

Tension in the tendons and jaw. Stretch and de-escalate deliberately.

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