Decanates and Duads

Does a planet in a sign have the same meaning in every horoscope? Yes and no.
Although everyone with a specific planet in a specific sign shares common characteristics, each displays subtle differences depending upon what degree the planet occupies within that sign. These differences explain why, for example, one person with Mercury in Capricorn is practical and another is more creative or family-oriented, or has a strong desire to be in the spotlight.
Both the three decanates (the ten-degree divisions of each sign) and the twelve duads (the two and a half-degree divisions of each sign) reveal sign characteristics specific to the individual, each of which is defined by the degree of the planet in the sign.
Using decanates and duads, you can discover much more about every planet in the horoscope, as well as the signs on the angles"the Midheaven, IC, Ascendant and Descendant. And this, in turn, will lead to new insights into relationships, career choice, communication style, finances and life purpose and goals.
