Hard metal heating in open light — capable, exposed, alert.
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 Wu day has Geng metal as their Day Master, sitting on the 午 (fire) branch.
Personality
Geng metal is decisive and principled; the Horse adds speed and visibility. You cut to the point, dislike vague commitments, and are sometimes judged more harshly than you expect because directness reads as force.
Work and vocation
Roles needing clean decisions under pressure: engineering, surgery, law, security, operations leadership.
Relationships
Loyal and protective, blunt in delivery. Softening the first sentence changes how the rest is received.
Health and rhythm
Heat and tension in the chest. Watch cardiovascular load and the habit of pushing through fatigue.

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