Vedic vs Western Astrology
The main difference is the zodiac. Western astrology uses the tropical zodiac, tied to the vernal equinox point. Vedic astrology uses the sidereal zodiac, tied to the stars. Due to precession, the difference between them is now about 24 degrees.
In practice, this means that most planets in the Vedic chart will be in the previous sign. A person with the Sun at the beginning of Libra in the Western system will have the Sun in Virgo in the Vedic system.
