The decans

Written by Alison

A decan is a subdivision of a zodiac sign, after it has been divided into 3 sections, each one being called a decan. As a sign lasts about 30 days, each decan therefore lasts about 10 days.

If you position the 12 signs round a wheel representing the zodiac, (starting with Aries, then Taurus… and ending with Pisces),these 12 signs each form:

-an angle of 30°, making up a zodiac circle of 360°
-a decan of 10° (12*3*10°) to form this zodiac circle.

De 0°00'00" à 9°59'59" : first decan
De 10°00'00" à 19°59'59": second decan
De 20°00'00" à 29°59'59": third decan.

Depending on your date of birth, you will have born during one of the three decans of a particular sign (see the chart below). The decans are associated with traits which reinforce or modify the essential characteristics of your zodiac sign.

For example, a Geminian born during the first decan will be more intuitive; one born in the second decan will be more energetic; and one born in the third will be more inclined towards the intellect and reasoning.
However, over the course of time, you are subject to the influence of planets transiting your sign. This influence will vary according to the decan of the sign under which you were born.

If the position of the planet Venus is at 16 degrees in the sign Sagittarius, this planet will have an influence on the Sagittarians born in the second decan, but not those born in the first and third decans. One can therefore imagine this magnificent Archer born in the second decan going through a charismatic and artistic period under Venus' influence - which will not necessarily be experienced by those born in the first and third decans.

Be careful, all the same! While it is easy to understand what a decan is, it is harder, though, to interpret the impact of the decans on a particular sign! It will involve making a precise and judicious analysis of your chart, paying attention to the position of the planets, their flow and influences, plus their surrounding astrological elements. This is how an experienced astrologer will really be able to determine the influences of these areas of the zodiac on your birth chart and tell you to what extent these will have an impact on you and when.
