NASA recently discovered the dates for the Zodiac signs were incorrect. There are actually 13 constellations in the original zodiac. Back when the signs were determined, the plans were drawn out for the 13 constellations to match the months of the year, but Babylonia already had a 12 month calendar. Since the Earth's axis no longer points the same direction, NASA has decided to add the sign back in. The new dates are:
Capricorn: Jan. 20 – Feb. 16
Aquarius: Feb. 16 – March 11
Pisces: March 11 – April 18
Aries: April 18 – May 13
Taurus: May 13 – June 21
Gemini: June 21 – July 20
Cancer: July 20 – Aug. 10
Leo: Aug. 10 – Sept. 16
Virgo: Sept. 16 – Oct. 30
Libra: Oct. 30 – Nov. 23
Scorpio: Nov. 23 – Nov. 29
Ophiuchus: Nov. 29 – Dec. 17
Sagittarius: Dec. 17 – Jan 20
