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.
