Fine metal in deep water, elegant and understated.
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 Hai day has Xin metal as their Day Master, sitting on the 亥 (water) branch.
Personality
Xin metal is refined; the Pig underneath adds openness and enjoyment. You are tasteful, generous, and more sensitive than the polished surface shows. You notice quality instantly and feel it when something is being done carelessly, including to you.
Work and vocation
Design, writing, finance, curation, or hospitality — work where taste and hospitality are the actual product.
Relationships
Affectionate and accommodating, and inclined to absorb discomfort rather than name it. Saying when something is not fine is part of the generosity.
Health and rhythm
Sleep, fluid balance and skin. Your body tends to register what you have decided not to bring up.
Upcoming 辛亥 days
The sexagenary day cycle repeats every sixty days. These are the next dates that fall on Xin Hai.
