The Ren day master (壬, rén)
Ren is Yang Water: a river, the sea, water that is already going somewhere.
Element: Water · Polarity: Yang · Pinyin: rén · Read as: a river, the sea, a running current
As a day master
A Ren day master is read as expansive, quick and hard to hold. It moves, it carries things with it, and it does not stay in the shape it was given.
What classically stands beside it
The classical line banks Ren with 戊 (Yang Earth, its Seven Killings) and lets 庚 (Yang Metal, its Indirect Resource) feed it; unbanked, a river floods its own fields.
Where it sits in a chart
The Day Master is whatever stem the day pillar lands on; a chart can carry the same stem in the year, month or hour pillar, and that is then read as another character standing to the Day Master, not as a second day master.
Where this stem comes from
The day is counted in an unbroken sixty-day cycle, so the stem is not chosen — it is the one the cycle lands on. Enter a birth date and the chart prints it.
Questions
How is the day pillar computed?
Days are counted in a cycle of sixty, unbroken since the calendar began, so a given date always falls on the same stem and branch. Only the hour pillar needs the birth hour.
Does a Ren day master mean I am Water?
It says the day stem is Water; the chart counts all eight characters. The Day Master is the reference point, not the whole of the reading.
