Ephemeris Dashboard
Swiss Ephemeris calculations laid bare.
Ephemeris Dashboard is an open-source Swiss Ephemeris calculator for astronomers, astrologers, and researchers. It provides precise planetary positions, house cusps, ayanamsa values, and fixed star data — all computed from the industry-standard Swiss Ephemeris library.
Features
- Planetary Positions — Sun through Pluto, plus lunar nodes, Lilith, Chiron, and more. Ecliptic longitude, latitude, distance, and speed for any date in history or the future.
- House Systems — Placidus, Koch, Equal, Whole Sign, Regiomontanus, Campanus, Porphyry, and many more. Cusps and angles (ASC/MC/ARMC/Vertex) computed for any location.
- Ayanamsa — Lahiri, Raman, Krishnamurti, Fagan-Bradley, and 30+ additional ayanamsa systems for sidereal calculations.
- Fixed Stars — Complete Sefstars catalog with positions and metadata.
- Flexible Input — Set date/time, geographic coordinates, and altitude. Choose tropical or sidereal zodiac, geocentric or topocentric, heliocentric or barycentric frames.
- Display Formats — View results in degrees-minutes-seconds, decimal degrees, or raw values.
- Multiple Themes — Dark, light, cosmic, and forest color schemes.
- Export — Save calculation results for your records.
No Interpretation
Pure astronomical values. No horoscope readings, no AI-generated meanings. Just the numbers.
Privacy
No accounts, no analytics, no tracking. Everything runs locally on your device.
Accuracy
Built on the Swiss Ephemeris (swisseph), the same engine trusted by professional astrologers and astronomers worldwide for over 25 years. When ephemeris data files are available, positions are computed to sub-arcsecond precision. A built-in Moshier analytical fallback ensures the app works even without data files.
