There are many differences between Western and Vedic astrology but one key difference is how the Tropical zodiac, mostly used in Western astrology and the Sidereal zodiac, mostly used in Vedic astrology, actually view the stars. It is the difference in degrees between where the vernal equinox is actually placed astronomically (6 degrees Pisces at present) and tropically as viewed by most Western astrologers on March 20, when the Sun is seen to pass through the first degree of Aries.
