Field notes
The page distinguishes astronomical facts from rulings: it says the tithi interval is solved to the second, then a resolver applies a cited rule, place, tradition, and profile. Its example cites CRC 1955’s General Rules for Religious Festivals and labels outcomes “Determinate,” “Boundary,” or “Decreed”; it also says alternative authorities appear beside rather than beneath a ruling. The page lists HTML, JSON, Markdown, ICS, and an MCP server among its machine-facing surfaces.
