According to Wikipedia, "Aries (♈) (meaning "ram") is the first astrological sign in the Zodiac, named for the constellation of Aries, called "The Ram" in the Greek tradition, after the golden ram that rescued Phrixos, taking him to the land of Colchis."

Furthermore, "in tropical astrology, this sign is no longer aligned with the constellation as a result of the precession of the equinoxes", further stated in Wikipedia. Under the tropical zodiac, the Sun is in Aries roughly from March 21 to April 19, by definition beginning at vernal equinox. Under the sidereal zodiac, it is currently there roughly from April 15 to May 15.
