Pisces (♓︎) is the twelfth and final astrological sign in the zodiac. It is a negative, mutable sign. It spans 330° to 360° of celestial longitude. Under the tropical zodiac, the sun transits this area between February 19 and March 20. In classical interpretations, the symbol of the fish is derived from the ichthyocentaurs, who aided Aphrodite when she was born from the sea.
