Three coordinates, three jobs

What the reference pillars contain

Each stem-branch pair is a deterministic calendar coordinate. Its role changes by pillar position, so the three rows stay separate rather than collapsing into one personality label.

Calculation boundary

What this date does not settle

The atlas uses a standard civil-date reference so dates can be compared consistently. A real birth happened at a place and an instant, not inside a URL slug.

  • Hour pillar: requires birth time after historical timezone and true-solar-time correction.
  • Day boundary: a late-night clock time can cross the adopted Zi-hour or solar-day boundary after correction.
  • Solar-term boundary: an actual birth instant near a term transition can change the resolved year or month pillar.
  • Interpretation: one date or one Jiazi pair does not determine career, relationships, wealth, health, or events.

Add birth time and birthplace. Pillarwise then resolves historical timezone, longitude correction, equation of time, day-boundary risk, and the hour pillar before it generates a chart.

What is the BaZi day pillar for Wednesday, May 16, 2007?

In this civil-date reference, the day pillar is 庚戌 (Yang Metal Dog), cycle position 47 of 60. A personal chart must still resolve the birthplace, local clock time, and day boundary.

The reference Day Master is 庚, Geng · Yang Metal. The Day Master is the heavenly stem of the resolved day pillar; it is not a complete personality result.

Can I calculate a complete BaZi chart from 2007-05-16 alone?

No. A complete Four Pillars chart requires birth time and birthplace. Historical timezone, longitude correction, equation of time, and hour or day boundaries can materially change the resolved chart.
