Eastern Sidereal Zodiac Signs - Cyril Fagan
The chart below can be used to determine your zodiac sign according to the Eastern Zodiac Dates. The Siderial Zodiac Dates are used primarily in India and elsewhere outside of the United States. Cyril Fagan assumed the origin of the zodiac in 786 BC, when the vernal equinox lay somewhere in mid-Aries, based on a major conjunction that occurred that year, corresponding to a difference of some 39 degrees or days. Most sidereal astrologers simply divide the ecliptic into 12 equal signs of 30 degrees but approximately aligned to the 12 zodiac constellations. Assuming an origin of the system in 786 BC, this results in a system identical to that of the classical tropical zodiac, shifted by 25.5 days. Tropical Zodiac is more commonly used in the United States and Western Europe.
