Soft water sharpened by precision — quiet, exact, penetrating.
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 You day has Gui water as their Day Master, sitting on the 酉 (metal) branch.
Personality
Gui water is intuitive and receptive; the Rooster adds standards and a sharp eye. You absorb atmosphere quickly and can be unexpectedly cutting when something is sloppy.
Work and vocation
Analysis, language, editing, quality control, therapy — roles where discernment is the skill.
Relationships
Perceptive and private. You notice everything; choose to say only what helps.
Health and rhythm
Fluid balance and sleep quality. Overthinking shows up in your body first.

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