Yin Water Day Master — 癸 (guǐ)
The Day Master is the heavenly stem of the day pillar: the sign that stands for you in a BaZi chart, the one every other sign is read against. There are ten of them, each element in a yang and a yin form. If you do not know yours yet, the calculator finds it from your birth date, time and place in a few seconds.
Traditional image
Yin Water is rain, dew, a spring in the rock: it falls softly, soaks in and reaches where a river cannot. The classics call it the water that nourishes without noise and say it needs metal as its source and earth as its vessel; too much dry earth drinks it up. The image is gentleness and persistence: the drop that wears the stone.
Three traits in this system
In this system a Yin Water Day Master is read as a chart with these leanings:
- Gentle, works without noise.
- Perceptive, reads moods and undercurrents.
- Persistent: returns until it gets through.
This is a reading by the rules of the system, for reflection and planning, not a statement about you. How much of it shows depends on the rest of the chart.
What supports it and what draws on it
Water is fed by Metal: signs of Water and Metal in the chart support a Yin Water Day Master. Wood is what it produces, Fire is what it controls, and Earth is what controls it: these three draw on it. In the app each of these relations has a name among the ten gods, and the library explains every one of them.
Water is in season in the first two months of winter (around 7 November to early January). In this system the month of birth weighs most in the strength of the Day Master, so a Yin Water Day Master born in its own season starts with the strongest support.
Strong or weak
In this system a Yin Water Day Master is read through source and vessel: the chart is asked whether metal keeps the spring flowing and whether earth holds the water or swallows it. With strong support it is read as a chart that reaches quietly where others cannot; with little support it is read as dew in the sun, and the planner looks for the periods that bring a source and shade.
How the app decides: it looks at the season of the month branch, at the roots of the Day Master's element among the stems hidden in the earthly branches, and at how many open signs support it against how many draw on it. The thresholds are published on the calculation method page, and next to every rating the app shows “why I see this”.
Its counterpart
Yin Water is the yin form of Water; the yang form is Yang Water. The two share an element and a season but are read through different images.
Find your Day Master
The calculator runs the same engine as the BaziArt app and does not store your birth data. The app adds the planner, the hour windows and the full chart with “why I see this” under every term.
