Those born between January 21 and February 18 are under the zodiac sign of Aquarius, the water-bearer. Aquarius is associated with the element of Air. Personality traits include progressiveness, independence and a desire to improve on the world around them. Aquarians are adaptable and intellectual. They spend much time involved in the world, and when in need of recharging they tend to pull away for some solitude. Never fear, the Aquarian will return refreshed and ready to jump back in.
