Decans are 10° divisions of the zodiac that add just a little extra flavor to the signs. With the decans of Leo, we get the influence of fire signs Sagittarius and Aries added to the second and third decans. Any planet located in Leo will receive the planetary influence of the Sun (Leo’s ruler) and a subruler (Sun, Jupiter, or Mars).
Leo is a fixed fire sign ruled by the Sun and holds sway over the 5th house in the natural wheel of the zodiac. A few keywords are:
The fifth house of your chart indicates love affairs, children, risk-taking or gambling, creativity, sportsmanship, and playfulness.
Dates for birthdays in the descriptions of the decans are approximate. You would need to consult an ephemeris or have your chart drawn to be sure.
First Decan Leo ~ 0-9.59°
This decan is both ruled and subruled by the Sun and, therefore, carries the purest Leo energy. Your birthdays range from July 22nd – August 1st, depending on the year. If you’re a New Moon baby (Sun and Moon in Leo), have your sun within first 2½ degrees of Leo, or you have your Sun and other planets in the 5th house, the influence of the Sun and Leo will be strengthened in your chart. Does the phrase Great Balls of Fire! mean anything to you? Goodness gracious! However do you discharge all that solar energy?
Second Decan Leo ~ 10-19.59°
Birthdays in this decan range from August 1st – 11th. This decan is subruled by the planet Jupiter, so it has a bit of a Sagittarian flare to it. Add a philosophical slant or a love of exploration to your Sun’s description. The strongest Sag/Jupiter influence will be found from 10-12.29° of this decan. Planets trining your Sun from Sagittarius will strengthen the influence, as will Jupiter in aspect to your Sun. Are you a second decan Leo with a 9th house Sun? Holy blazes! No wonder you feel at home there.
Third Decan Leo ~ 20-29.59°
Here are the Arian Leos, born August 12th-23rd. You are subruled by Mars and have a little bonus that comes with that. The Sun is exalted in Aries, meaning it finds great ease of expression there. With the Aries influence, you are a true dynamo and a fierce defender of those you love. More timid souls may find you too hot to handle at times, but may also find your leadership qualities hard to resist. The strongest influence of the subruler in this decan will be found at 20-22.29°. If Mars is aspecting your Sun, you have other planets in Aries, or you have a first house Sun, this influence will be felt more intensely.
Duads of Leo
Each sign can be also be divided into 12 sections, with each 2½° falling under the rulership of a sign and planet. To determine the duads, always start with the first 2½ degrees belonging to the sign’s ruler and then progress through the zodiac. This is a much subtler influence than the decan’s ruler, but may give you a better understanding of any planet placed in Leo. Starting degrees are noted for each duad.
