Mainstream astrology uses the 12 - sign zodiac , dividing the sky into 12 sectors with each sign corresponding to the location of sun through a star group . The idea of a 13 - sign zodiac was propagated through the publication and promotion of a 1995 book " The 13 Signs of the Zodiac " by Walter Berg and Mark Yazaki , which was a bestseller in Japan .

Ophiuchus has sometimes been used in sidereal astrology as a thirteenth sign in addition to the twelve signs of the tropical zodiac , because the eponymous constellation Ophiuchus ( Greek " Serpent - bearer " ) as defined by the 1930 IAU constellation boundaries is situated behind the sun between November 29 and December 17 .
