March 21st - April 20th
Particularly, they find interest in sports, politics, and anything else pertaining to good competition. It's very possible that they'll gain public recognition (Sun) through competition (Aries). Good placements for Mars indicate healthy competition; Jupiter increases the chance for recognition. The opposite is possible for an afflicted Mars as well as a lack of connections in Jupiter.
The newness of Aries comes from it being a Cardinal sign as well as the first in the zodiac. They specialize in beginnings; first experiences are Aries' comfort zone because they're so enthused about learning new things. Their hunger for experience makes them come off as inexperienced, so they may need guidance from others. Because of their need to experience things at the front lines, Aries do not take well to being told what to do; they want to find their own way, not pointed in a particular direction.
The sign Aries is ruled by Mars. Mars is extremely primal, working completely off of reactions and almost nothing else. That makes Aries an initial sign, completely on the surface and little else. If there are especially sensitive signs coating the emotions and subconscious of Sun in Aries natives, they may come off as egotistic, overconfident, and immature as a form of protecting themselves.
A Healthy Aries Sun
If the sun and Mars is in good standing, natives with a Sun in Aries will be leaders, strong-willed, and protective. They have no issue with taking the reins in any situation, and because the sun is already in good standing in Aries, this is the case most of the time. Mars is a warrior planet, and Aries is its soldier, which makes Aries a protector of those they love. The strong will of Aries comes from the luminescence of the sun; no other planets would shine without the light of it.
An Afflicted Aries Sun
If the sun and Mars is afflicted, natives with a Sun in Aries will be extreme, egotistical, and quick to react. They're known for their anger, extreme reactions being a basic part of the personality. Arrogance in sports and other competitive occupations may lead to their undoing. Egotism comes from insecurity and need to feel bigger or more important than others; the native may not even realize these qualities about themselves, especially if those around them do not point it out.
