(Because of the moon’s gravitational pull, Earth is currently in a different spot in relation to the sun, and its equatorial alignment has changed from 3,000 years ago when the study of astrology began -- back when 12 zodiac signs were assigned to 12 different periods of the year. Which means that a Virgo may now be a Leo, an Aquarius - a Capricorn, and a Taurus - an Aries.
To confuse matters even further, he added a new horoscope, Ophiuchus.
So using this theory your "up to date" horoscope, reflecting where the stars currently are aligned, is:-
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
Of course, in the great tradition of the internet, this has been debunked, with astrologers round the world pointing out that astrology is based on the four seasons, not on constellations -- and the seasons don't change. Well, I don't know if they've noticed, but I was sitting outside in my t-shirt this weekend, and it's only March!
Update -If you still believe in your daily stars, and the personality traits assigned you, read the fact for the 29th March.)
