The Western astrological sign of Aquarius forms part of the tropical zodiac (January 20 – February 18) and of the sidereal zodiac (February 13 – March 14).
Aquarius is associated with the classical element Air, and thus called an Air Sign (with Gemini and Libra). It is also one of the four fixed signs (along with Taurus, Leo and Scorpio). Its polar opposite is Leo. It is the domicile of Saturn and Uranus. Aquarius's symbol is the water-bearer.
As an Air sign, Aquarius is associated with thought, perspective and communication. In combination with the other elements, air feels that water will obscure it, earth will suffocate it, but fire will inspire and uplift it. As a Fixed sign, it is associated with focus, individuality and determination.
