The first decan of Aries covers roughly March 21 to March 30. Every sign is split into three decans of about ten days each, and while all of them are Aries at heart, each decan carries a different planetary sub-ruler that colours the sign in its own way.
Aries decan 1: sub-ruled by Mars
The first decan is ruled by Mars, the natural ruler of Aries itself, so this is the purest, most concentrated expression of the sign. If you are born here, you are Aries through and through, with extra drive, courage and a competitive, take-charge edge dialled all the way up.
Aries decan 1 personality
The bold pioneer who charges first and asks questions later. As the first sign of the zodiac, Aries is all about beginnings, drive and raw energy. Ruled by fiery Mars, the Ram leads with courage, acts on instinct and rarely backs down from a challenge. In the first decan, that Aries essence is shaped by Mars: you keep the courageous and confident core of the sign, with an added boldness that sets you apart from the other Aries decans.
Strengths of Aries decan 1
At its best, the first decan keeps the courageous, confident, passionate strengths of Aries and adds an extra dose of boldness from Mars, a blend the other two decans do not carry in the same way.
Challenges of Aries decan 1
The growth edge of this decan is impatience and a quick temper, the shadow side of its Mars sub-ruler. Spotting it early stops it from undercutting the courageous core of Aries.
Love and compatibility
In love, Aries is most compatible with Leo, Sagittarius, Gemini, Aquarius. The Mars influence of this decan means you bring extra drive, courage and a competitive, take-charge edge to your relationships, on top of everything else that makes Aries who they are.
Aries decan 1 at work
At work, the first decan of Aries channels Mars into drive, courage and competitiveness, pushing hard, leading from the front and doing best with a challenge to win. That is what gives this decan a slightly different professional edge from the other two.
