What the reference pillars contain

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.
