Four
Pillars
Resolve the four pillars from solar civil time and exact solar-term boundaries. The interface exposes the selected day sect and separates timezone resolution from traditional solar-time corrections.
Level 1 · Overview
Civil time parameters
The module accepts solar civil input, verifies its IANA offset, and keeps civil-time and traditional boundary choices explicit.
The four pillars will appear here.
Choose the exact civil time, timezone and day boundary. The result presents stems, branches, ten gods, hidden stems, stages and solar-term evidence.
