Sidereal Astrology Explained

Sidereal calculations, unlike popular astrology, take into account the precession of the equinoxes. Precession is caused by a slight wobble of the earth's axis, which makes the planets appear to move back in the sky by one degree every 72 years.

Sidereal calculations are based on where astronomers actually observe the planets to be in the sky in 2008, with their scientific instruments, rather than where the planets were historically without precession being taken into account.

In the year 2008, all of the planets have moved back by about 25 degrees from the positions used in popular astrology, which was accurate only in the year 221 A.D., when the "popular" system was introduced in ancient Greece.

If you work with your sidereal chart, you will be amazed at its increased level of accuracy!

Here are the approximate dates for each sidereal sign:

Aries - April 14 to May 15
Taurus - May 15 to June 15
Gemini - June 15 to July 17
Cancer - July 17 to Aug. 18
Leo-Aug. 18 to Sept. 18
Virgo - Sept. 18 to Oct. 18
Libra - Oct. 18 to Nov. 17
Scorpio - Nov. 17 to Dec. 17
Sagittarius - Dec. 17 to Jan. 15
Capricorn - Jan. 15 to Feb. 14
Aquarius - Feb. 14 to March 15
Pisces - March 15 to April 14

If you are a Libra in popular astrology, you are most likely really a Virgo in sidereal astrology, unless you were born in the last 5 degrees of "popular" Libra (each sign being 30 degrees).
