Has your horoscope been really off? It may not be the astrologer’s fault. It may be the universe’s.

Fort Myers’ NBC affiliate WBBH reports that according to astronomer Parke Kunkle, Earth is 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.

Astrological signs are different now because the Earth’s wobble on its axis has created a one-month bump in the alignment of the stars, according to Kunkle.

“Because of this change of tilt, the Earth is really over here in effect and Sun is in a different constellation than it was 3,000 years ago,” Kunkle is quoted as telling WBBH.

The shifting around has created a 13{+t}{+h} sign in the constellation Ophiuchus, the serpent bearer.

Here are the new signs:

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

While this is bad news for everyone who’s been getting bad advice from their horoscope, it may be good news for people who make items with zodiac signs on it: their product line has just expanded.

So, what’s your new sign? And will this affect how you read your horoscope?
