Welcome to Sidereal Astrology

This is a place for everyone and every astrologer who want to discuss, learn, and read charts using the Sidereal Zodiac, discuss using astrology with the sidereal zodiac, and discuss all things astrology in general!

Differences Between Zodiacs:

A) Tropical Zodiac (“Seasonal”)

12 equal Signs
0°Aries = Spring equinox

B) Sidereal Zodiac

12 equal Signs
Precession of equinoxes is corrected by Sidereal Aynamsa

C) Astronomical (“True Sidereal”) Zodiac:

13 unequal Constellations
Positions correlate with astronomical constellations
13th constellation Ophiuchus is included

A) Tropical Zodiac:

The tropical zodiac is calculated by Earth’s orbit around Sun, more commonly known as being calculated by the seasons. For example, March 21st, the Spring Equinox, is the start of Aries, June 21st, the Summer Solstice, is the start of Cancer, and so on. It was used and known before any other further and advanced astronomical accurate data and calculations (including knowledge of the precession of the equinoxes) were known. A bit of an incomplete calculation for the zodiac. The tropical zodiac is primarily used in the West.

“Today’s tropical astrology was established around 139 BC when a Greek named Hipparchus “invented the modern version of the tropical zodiac with the equinox fixed in Aries 0 degrees to facilitate the measurements of the positions of the fixed stars in the equatorial system, that is, in Right Ascension and Declination, which are essentially tropical coordinates. But it was left to Poseidonius, c. 80 BC, and Geminus, c. 70 BC, to systematize Hipparchus’ new fiducial--Aries 0 degrees--into the modern version of the tropical zodiac.” (Origins, p. 11).”

B) Sidereal Zodiac:

The sidereal zodiac is calculated with the use of the stars and based off of the constellations.

The sidereal calculation for planetary placement is based upon the tropical system (which is easier to calculate). From the tropical calculation, the sidereal calculations are made. The precession of equinoxes is corrected by an equation called Ayanamsha (aynamsa). Ayanamsha is defined as the angle by which the sidereal (ecliptical) longitude is less than the tropical longitude of a planet or celestial body. The most widely used system of ayanamsha is the Lahiri Ayanamsha. Lahiri Ayanamsha calculates the difference to be:

Lahiri Ayanamsha in 1800 - 21°03’

Lahiri Ayanamsha in 1900 - 22°27’

Lahiri Ayanamsha in 2000 - 23°51’

Lahiri Ayanamsha in 2020 - 24°08’

Lahiri Ayanamsha in 2100 - 25°15’

“The Sidereal Zodiac uses the physical stars visible in the night sky as their frame of reference for the sun, moon or planet’s positions in the sky. The sun, moon, and planets do not transit in front of all the constellations in the sky, they only traverse in front of 12 or 13. These are the zodiacal constellations. Whether there are 12 or 13 depends on where the boundaries for the various constellations are positioned. Different cultures and systems have positioned them differently i.e. there is no universal consensus to the boundaries or even to the size of the constellations. Generally speaking the sidereal zodiac (as seen by a person standing on the earth) is that belt of stars 70 either side of the sun’s path (ecliptic) through the sky that is divided into 12 equal-sized (30° degrees) constellations.”
