Term: Sidereal Zodiac

Due to slight changes in the movement of the Earth around its axis, the positions of the stars in the sky relative to the equinoxes and solstices slowly change in what is called the Precession of the Equinoxes. In the common Western form of astrology, which uses the Tropical zodiac, the Vernal Equinox always is associated with 0 degrees of the sign Aries. With the Sidereal Zodiac, which is found in other forms of astrology such as Jyotish, the astrology of India, the equinoxes and solstices move slowly backward through the signs of the Zodiac at a rate of one degree between 70.59 and 72.15 years.
