Signs

The twelve signs of the zodiac, sidereal and tropical — their elements, rulers, temperaments and the difference between the two zodiacs.

The zodiac is a circle of twelve equal signs, each thirty degrees wide. Vedic astrology measures it against the fixed stars (sidereal); Western astrology measures it from the spring equinox (tropical). Today the two differ by about twenty-four degrees, which is why your Vedic and Western signs often disagree — both can be read honestly, as long as we say which one we mean.
