FAQ
Is Astreya as accurate as Astro.com (Astrodienst)?
Yes for the underlying math - both use Swiss Ephemeris derived from JPL DE431 for planetary positions, and both default to Placidus houses in the West. The difference is presentation: Astro.com surfaces raw wheels and tables; Astreya adds narrated interpretation, Vedic dashas, Human Design, numerology, tarot and dream work in one bilingual experience.
Does Astro.com include Human Design or Vedic dashas?
Astro.com offers Vedic charts (Lahiri) but no full Vimshottari dasha timeline in the free tier, and no Human Design bodygraph at all. Astreya includes both, plus numerology and tarot, and translates every report to Bulgarian.
Is Astreya open about its methodology?
Yes - Placidus (Western), Whole Sign + Lahiri (Vedic), JPL Horizons for Chiron, IAU 2006/2000A precession/nutation - all documented on the About page and in the /rechnik glossary.
Which is better for a beginner?
