Astronomical Differences Between Western and Vedic Astrology

Vedic astrology and Western astrology differ with each other on several points. And one such difference is the difference between the astronomical calculations. This is a basic difference between the two systems. The Vedic zodiac is sidereal and the Western zodiac is tropical. If you go by both, you will definitely end up reaching no conclusion. The Vedic zodiac is aligned with 27 constellations, or fixed star groups, in sidereal astrology. Aries, the first sign of the zodiac, aligns with the first constellation, called Aswini. While in the tropical zodiac, the point in space is the beginning point of the zodiac. Aries, in this zodiac, aligns with the Sun, when it crosses the earth's equator. This is the basis of calculations in both the types of astrology. Have you understood now, the reason behind such great rifts between the two?
