The inclusion of a 13th Zodiac in Astrology is just -NOT- true.
Take note of this:
“In the Western or tropical zodiac, the Sun enters the tropical sign Aries the day of the vernal equinox each March. That’s the day that the Sun’s rays meet the equator directly overhead — the first day of spring in the Northern Hemisphere. (In the prior draft and in the audio I said ‘at a right angle’. Same idea.) The Sun enters the tropical sign Cancer when the Sun’s rays square the Tropic of Cancer — the first day of summer in the Northern Hemisphere, or summer solstice. The Sun enters Libra when the Sun’s rays square the equator again in September. The Sun enters Capricorn when the Sun’s rays square the Tropic of Capricorn each December, which is the first day of winter in the Northern Hemisphere (the seasons are reversed in the Southern Hemisphere).”
“You then take those four cardinal points and divide them equally and you have the 12 signs of the tropical horoscope. There are no ‘extra signs’ added — the tropical zodiac is a division of the 360-degree wheel of the year into 12 equal slices of 30 degrees. This is not rocket science — but it is science.”
