Swiss Ephemeris

Swiss Ephemeris is widely used in professional astrology software because it provides high‑precision planetary positions. In Seven Deadly Sins Clock, Swiss Ephemeris can be used via WebAssembly (WASM) for maximum accuracy.

Why accuracy matters

• Fast points (Moon, Ascendant, house cusps) change quickly; timing matters.
• Accurate longitudes reduce drift in aspect detection and entry/exit boundaries.
• Consistency helps when comparing zodiac systems and house models.
