Tropical zodiac meaning in astrology: seasonal zodiac

Western astrology commonly uses it.

Its starting point moves slowly against the fixed stars because of precession.

Modern ephemerides (tables of planetary positions) give tropical positions, and Vedic astrology subtracts the ayanamsa to get sidereal ones.
