Zodiacs

Tropical Zodiac

This system is most commonly used in Western astrology. It is the moving zodiac where the equinoxes and solstice points stay at the same zodiacal degree from year to year, keeping in step with the seasons.

Sidereal Zodiac

This system is most commonly used in Eastern astrology. This is the fixed zodiac where the equinoxes and solstice points move slowly back through the zodiac from year to year, due to precession which occurs at the current rate of about one degree every 71.85 years. Over long periods of time, the precessional rate can vary slowly between one degree every 70.59 years, to one degree every 72.15 years.
