BaZi · Day Master
The Bing day master (丙, bǐng)
Bing is Yang Fire: the sun itself, light that falls on everything without choosing.
Element: Fire · Polarity: Yang · Pinyin: bǐng · Read as: the sun
As a day master
A Bing day master is read as open, visible and generous, with little that is hidden and little that is calculated. What it shows is what it is.
What classically stands beside it
The classical line sets Bing against 壬 (Yang Water, its Seven Killings) for the sky-over-water contrast, and warns that a sun with nothing to reflect on burns itself out.
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 Bing day master mean I am Fire?
It says the day stem is Fire; the chart counts all eight characters. The Day Master is the reference point, not the whole of the reading.
