The Mathematics of Astrology

This prezi shows just how much math goes into astrology, the pseudo scientific way of determining your future through the positions of the planets, stars and the Sun.

Transcript of The Mathematics of Astrology


Each Zodiac sign marks the amount of space the sun moves from the viewpoint of the Earth, in the amount of time it takes to complete one moon orbit.
Each sign therefore holds 30º of space, since 30 x 12 = 360.
Lunar Mansions
Second, there are the 27 Lunar Mansions, they are determined by the amount of space the moon moves in one day, 12 1/3º. There are exactly 9 Lunar Mansions per 4 Zodiacs, this causes the chart to have three distinct sections as the movement of the moon corresponds to the movement of the sun.
Third, each Zodiac is divided into 9 sections - Navamsha, this is important as each Zodiac has exactly 9 and each Lunar Mansion has exactly 4 sections and 3 1/3º in length. The resulting amount of sections is 108 which is an important occult number, and has been throughout history and in many different religions.
Fourth, each Zodiac is sub divided into five categories - Avastha, each spanning 6º in the chart, they represent the five stages of life:
Near death
Sixth, divide each Zodiac into three sections - Drekkan, plural Drekannas, each spanning 10º. The sign of each division starts with the sign it is the division of, the next sign is the 5th sign from it and the final sign, the 9th sign for it.
Ex. Aries' Drekkannas:
1. Aries
2. Leo
Astrology relies on the use of charts in order to determine the signs in the heavens. However, in order to construct those charts, astrology uses a lot of math.
The Mathematics of Astrology
First, there are the main 12 sections, the zodiac. The reason why there are twelve is based on how many times the Earth spins while it turns one full orbit around the sun. The answer is roughly 360 times.

During the course of the Earth’s orbit, the moon will orbit the Earth roughly 12 times, that’s why we have 12 months, 1 month for a full moon orbit.
Mystic 108
The earth cycle is supposed to be of 2160 years = 20 x 108.
The distance between the Earth and Sun is 108 times the diameter of the Sun. The diameter of the Sun is 108 times the diameter of the Earth
The distance between the Earth and Moon is 108 times the diameter of the Moon.
There are 12 constellation and 9 arc segments. 9 times 12 equal 108.
The 9 planets travelling through the 12 signs constitute the whole of existence. 9 x 12 = 108.
Fifth, each Zodiac is split into two called Horas, each half governed by either the Sun or Moon, in a male sign, it's the first half that is Sun, while in a female sign, it's the second half that is Sun. To determine the gender of a Zodiac, number the Zodiacs starting with Aries which is 1. All odd numbers are male while all even numbers are female.

Seventh, each Zodiac is divided yet again, but into 5 unequal parts called Trimsha. In male signs the order of the Trimsha goes Mars, Saturn, Jupiter, Mercury and Venus. In female signs, it is the opposite. The way in which things are ordered, go anti-clockwise, with the first sign leftmost.

There are a few more divisionals, such as the 7 part divisional Saptamsha, the 10 part divisional Dashamsha, the 12 part divisional Dvadashamsha, the 16 part divisional and the 60 part divisional and even more.
You might think that astrology might seem wishy washy and fairy dumb to believe in, but it’s very complicated and mathematical wishy washy.

Astrologers would calculate the positions of the planets using a device called an astrolabe and with math and knowledge of how fast they traveled, the would determine when a planet would arrive at a particular place. This allowed them to know when a planet would change from one sign to another and from one house to another. Doing this for two planets they could determine when they would be in aspect to each other.
Math is used to construct astrological charts.
The most complex forms of math used for all this is spherical trigonometry and spherical geometry.
