Vast soft water, generous and hard to measure.

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 Gui Hai day has Gui water as their Day Master, sitting on the 亥 (water) branch.

Personality

Gui water is intuitive; the Pig underneath adds warmth and generosity. You are imaginative, adaptable and quietly persistent, with a wide tolerance for ambiguity that others find either soothing or evasive. You understand situations long before you can explain them.

Work and vocation

Writing, design, therapy, research, or hospitality — work that rewards sensitivity and punishes constant noise.

Relationships

Warm and accommodating, which makes boundaries feel like a betrayal. They are not; a clear limit is what allows generosity to last.

Health and rhythm

Fluid balance, sleep and digestion. Your energy registers other people’s moods, so recovery often means time alone rather than more input.

Upcoming 癸亥 days

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