Three Birth-Time Scenarios
| Data status | Reliable output | Remaining uncertainty | Recommended handling |
|---|---|---|---|
| Exact local hour | All four pillars | Timezone, daylight saving and solar-term boundaries still need checking | Use birthplace and preserve the original record. |
| Only morning or evening is known | Three fixed pillars plus several candidate Hour Pillars | Ten Gods, element balance and Hour themes may change | Compare candidates side by side without forcing one. |
| Time completely unknown | Year, Month and Day Pillars | Every detail that depends on the Hour Pillar | Label it as a no-hour chart and interpret only stable parts. |
