Astrology and astronomy are the same discipline
Both study planets, so astrology is simply another branch of astronomy.
Astronomy is a physical science. Astrology is an interpretive tradition that assigns meaning to celestial positions.
Why the distinction matters
The two share historical roots and astronomical calculations, but they ask different questions and use different standards of evidence. AstroRoshni uses astronomical position data to construct charts; the interpretation of those charts belongs to Vedic astrological tradition, not modern astronomy.
