Your new zodiac sign

From http://www.boston.com/news/source/2011/01/new_zodiac_sign.html?rss_id=Top+Stories

The stars are not aligned, apparently.

Thanks to the moon's gravitational pull, zodiac symbols -- the age-old constellations that correspond to a person's birthday -- are off by about a month.

Here are the corresponding changes, according to The Washington Post:

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-Dec. 17
Sagittarius: Dec. 17-Jan. 20

As if this weren't confusing enough, there's talk about adding a 13th sign to the mix -- Ophiuchus, which would span Nov. 29 - Dec. 17, leaving poor Scorpio with only a tiny, six-day window (Nov. 23 - Nov. 29).
