Earth Alignment and Changing Chinese Zodiac Sign

New Zodiac Sign Ophiuchus

On January 12, 2011, astronomer Parke Kunkle told NBC News that the astrological signs have changed due to the changes in the Earth’s alignment. The reason is that 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. Now we could have been using 13 astrology signs. They could look like this:

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.

Tropical Zodiac and Sidereal Zodiac

Many different zodiacs were invented with their calendars, all to measure the positions of celestial bodies. Tropical zodiac uses the calendar based on the sun. Sidereal zodiac uses the sidereal calendar based on a faraway fixed star, which provides a more accurate birth time. That's the difference between tropical zodiac and sidereal (fixed) zodiac. Today most astrologers use the tropical zodiac. However, Parke Kunkle talks about the sidereal zodiac.

The path of the Sun around the Earth is called the ecliptic. In the tropical zodiac, the earth is represented by a dot of at the center. The greater circle divided into 12 signs in the apparent path of the Sun around it. In the astrology positions of planets (Sun, Moon and other planets) are almost always measured on the ecliptic.

In the sidereal calendar for astronomy and navigation, the equator is another great circle defined by its equidistance between the north and south poles of the Earth. Because these are different measurements, certain astrologers might tell you that instead of being born as an Aries according to the tropical zodiac, you were really born as a Pisces according to the sidereal calendar.

The sidereal zodiac is not new. The first Egyptian and Babylonian zodiacs were of the fixed, sidereal type. There were debates between tropical and sidereal zodiac in the past, but only a few astrologers use sidereal zodiac in the west today.

No Change for Chinese Astrology

Chinese Five Element astrology uses the solar calendar, which is a tropical zodiac. There are no other planets involved but the Sun in Chinese Five Element astrology. Therefore, Chinese astrology doesn't have any impact because of changes in the Earth’s alignment. How the Chinese astrology calendar is calculated? The answer is at the Chinese Lunar Calendar page.
