Astrology
Astrology is the symbolic study of the position of celestial bodies and their claimed relationship to events and human traits. The 12-sign zodiac originated in first-millennium BCE Babylon and was systematized by the Greeks — from there, different traditions (Western tropical, Vedic sidereal, Chinese) developed distinct and sometimes divergent ways of interpreting it.

Frequently asked questions
- Is astrology a science?
- No. Astrology is a symbolic and cultural system with no support from modern empirical science — distinct from astronomy, the science that studies celestial bodies. This site treats astrology as a historical and cultural phenomenon, documenting its traditions without claiming predictive validity.
- Why do the tropical and Vedic zodiacs have different dates?
- Because of the precession of the equinoxes — a slow shift in Earth's axis that, over millennia, has misaligned the tropical zodiac (fixed to the seasons) from the sidereal zodiac (fixed to the constellations). Today the gap is roughly 24 degrees, nearly a full sign's width.
