The reference place makes no effect, as the age harmonic chart operates purely with the birth chart.Īs might be expected, number symbolism is an important factor when it comes to interpretation: The number of the harmonic and the aspect resulting from the division of the circle - in the above example the quintile - indicate the quality of the theme in question. The age factor is determined by the number of days since birth, divided by the length of the tropical year.Įach ecliptic longitude is multiplied by the age factor, and then reduced with modulo 360 to the range. This number gives the position of the horoscope factor in question. If the result is a number larger than 360, then 360 is subtracted as many times as is necessary from this number until a number below 360 is reached.

(The absolute number of degrees is always measured from 0 degrees of Aries for example, the absolute number of degrees for 23 degrees of Gemini is 83 degrees). The following procedure is used to calculate the positions of the planets, Ascendant and Medium Coeli in the harmonic chart: The absolute number of degrees of each horoscope factor is multiplied by the harmonic number - in this case 5. Any resulting oppositions were semi-quintiles (36 degrees) in the natal chart and a trine in the harmonic chart was a 3rd of a quintile (24 degrees) in the natal chart. All the planets that formed quintile or biquintile aspects in the natal chart now come together to form conjunctions. What remains is a 72 degree segment which is then expanded out again to form a whole circle. These five segments are then laid on top of each other so that the planets which form quintiles or bi-quintiles to each other in the original chart come together. Each of the 5 segments contains the whole zodiac, always starting at 0 degrees of Aries.

The resulting aspect is the quintile (72 degrees) the fifth harmonic is concerned with the quintile and bi-quintile. the 5th harmonic) is used to illustrate the principle: The 360 degree circle is divided into 5 segments. It is theoretically possible to do this with any number, but in practice the most common harmonics astrologers work with are the 4th, 5th, 7th, 8th and 9th. In order to create a harmonic horoscope the 360 degree circle is divided by the number of the particular harmonic.
