The 12 astrological signs of the Zodiac do not fall neatly into the 12 months, but instead overlap from around the 19th to the 23rd of one month to around the 18th to the 22nd of the next. The dates of each astrological sign are as follows: Aries, March 21 to April 19; Taurus, April 20 to May 20; Gemini, May 21 to June 20; Cancer, June 21 to July 22; Leo, July 23 to August 22; Virgo, August 23 to September 22; Libra, September 23 to October 22; Scorpio, October 23 to November 21; Sagittarius, November 22 to December 21; Capricorn, December 22 to January 19; Aquarius, January 20 to February 18 and Pisces, February 19 to March 20. People born in different months may therefore share the same astrological sign.
Along with the constellations they represent and are named for, each sign is associated with an element, a set of personality traits and ruled over by a celestial body. Cancer, for example is a water sign, ruled by the moon and associated with personality traits such as stubbornness, emotion and intimacy. Leo, ruled by the sun, is a fire sign associated with extroversion, generosity and leadership.
Capricorn, an earth sign, is ruled by Saturn. People with this sign are expected by astrologists to be purpose-driven, persevering and ambitious. An example of an air sign, Libra is ruled by Venus and associated with a desire for harmony.
