Polished metal catching heat and glinting sharply.
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 Xin Si day has Xin metal as their Day Master, sitting on the 巳 (fire) branch.
Personality
Xin metal is discerning; the Snake adds intuition and strategy. You have high standards, read people quickly, and prefer influence behind the scenes to open confrontation.
Work and vocation
Design, law, finance, editing, consulting — precision work with high stakes.
Relationships
Selective and observant. You give trust slowly and withdraw at the first sign of carelessness.
Health and rhythm
Nervous tension and shallow breathing under stress.

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