Aries · 1st decan
Born on March 21, your Sun sits in Aries — Bold, energetic, and always first to act. More precisely, March 21 falls in the 1st decan of Aries, where the sign runs purest — sub-ruled by Mars, doubling down on drive, courage and a forward push.
Personality & character
If you were born on March 21, you carry the raw initiating spark of the zodiac's first sign — a need to begin, to move, to be first through the door before anyone has finished deliberating.
As a fire sign you run on enthusiasm, instinct and momentum — you lead with action and warmth. Your cardinal modality makes you an initiator — you start things and set directions in motion.
As a 1st-decan Aries, you express the sign in its purest, most undiluted form — sub-ruled by Mars. Mars lends drive, courage and a forward push to the core Aries character, shading how the sign's themes actually show up in your day-to-day temperament.
Your Sabian symbol
Every degree of the zodiac carries a Sabian symbol — a single vivid image, set down in 1925, that colours that exact point of the sky. A March 21 birthday places your Sun near Aries 1°, whose symbol is:
“A woman rises out of water, a seal rises and embraces her”
March 21 in love
In love you are direct and ardent. You pursue rather than wait, and you want a partner who can keep pace without dimming your fire. The chase excites you; what tests you is staying once the conquest is won.
March 21 in career
At work you are a starter, not a finisher — brilliant at launching, restless once the novelty fades. You thrive where speed and courage are rewarded and authority isn't waiting to slow you down.
