What is the Difference Between Vedic Astrology and Western Astrology?
The main difference between Western astrology and Vedic astrology is the way the position of the planets are measured along the belt of stars called the zodiac. Western astrology uses the tropical zodiac, which is based on the position of the sun. this system takes the first day of spring (around March 21), as the entrance of the sun into the first degree of Aries—regardless of where the sun actually is against the backdrop of the sky. In contrast, Vedic astrology uses the sidereal zodiac, in which the stars are fixed. The sidereal zodiac is based on the fixed-star constellations, and it measures the actual astronomical positions of planets against those constellations. In this system, the sun’s entrance into Aries is marked by the sun passing through the observable fixed stars of the constellation of Aries.

What is the difference between the tropical and sidereal zodiacs?
While these two measurements of the sky coincided more than 2,000 years ago, a difference in measurement has accrued since then of about 24 degrees. This difference is caused by a phenomena called the “precession of the equinoxes,” which makes it so that the point of the vernal equinox drifts back slowly in relation to the fixed stars. There is almost one entire zodiac sign of variance between them! Due to this difference between the two zodiacs, it is usually surprising for most people to find out that their ascendant, sun, moon, and other planets are often in different signs in both the systems.
