Pure fine metal, exact and self-reflecting.
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 You day has Xin metal as their Day Master, sitting on the 酉 (metal) branch.
Personality
Xin metal is precision; the Rooster underneath is standards. You have a sharp aesthetic and moral eye, and you notice what is off before you notice what is right. That makes you excellent at quality and occasionally hard to live with, because refinement is not the same as fault-finding.
Work and vocation
Design, editing, law, finance, medicine, or fine craft — work judged on detail, where “almost right” is a failure.
Relationships
Devoted and exacting. Appreciation spoken aloud matters more than you assume; people cannot infer approval from the absence of criticism.
Health and rhythm
Lungs, skin and sleep. Perfectionism shows up in the body as tension in the chest and a mind that will not clock off.
Upcoming 辛酉 days
The sexagenary day cycle repeats every sixty days. These are the next dates that fall on Xin You.
