Aries decans

Aries spans 30 degrees, and astrologers traditionally divide every sign into three 10-degree decans. It is where the “March Aries” versus “April Aries” distinction comes from. The dates below are approximate: the sun does not move at a perfectly even rate, so a cusp can shift by a day either way from year to year.

Aries Man

The Aries man moves like he's already late for something important. Cardinal fire, ruled by Mars — there's an impatience baked into him that never quite settles, even when he's sitting still. He's the one at dinner who's already floated three new ideas before the appetizers arrive, genuinely thrilled by his own momentum, and a little bewildered when others aren't. He competes. Not always viciously, but constantly — with colleagues, with strangers in traffic, occasionally with himself from six months ago. He keeps score in ways he won't fully admit to. The thing people miss is how direct he is as a form of respect. He won't maneuver or hint. If he disagrees, you'll know. If he's interested, he'll say so. That bluntness can land badly, and he rarely stops to wonder how it landed. He burns hot and moves on fast, which makes him thrilling to be around in a crisis and occasionally exhausting on a Tuesday.

Aries Woman

The Aries woman has a very clear sense of what she wants, and she's not in the habit of softening that for anyone's comfort. Mars-ruled, cardinal fire — she initiates. Plans, conversations, confrontations. She's not aggressive exactly, but she has a forward gear and she uses it, and the idea of waiting for someone else to take the lead strikes her as genuinely strange. She's competitive in a way that surprises people who expected something quieter. Put her in a room where someone's condescending to her and watch the temperature shift. She won't perform patience she doesn't feel. What makes her genuinely good company is that the same directness cuts both ways — she'll champion you as fiercely as she'll challenge you, and there's no calculation behind either. She gets bored with people who are too cautious to be honest. Six months into a friendship, she'd rather have the real argument than the polite nothing.

The fire signs

Aries shares the fire element with Leo and Sagittarius. Signs of the same element are traditionally read as sharing a basic temperament — the way they take in and give out energy — even where the rest of the chart differs.

The cardinal signs

Aries is cardinal, alongside Cancer, Libra and Capricorn. Modality describes how a sign meets change: cardinal signs start things, fixed signs hold and sustain them, mutable signs adapt and let go.

Traditional compatibility

Fire and air signs are traditionally described as energetically compatible with each other, which puts Aries alongside the air signs below. Treat this as a starting heuristic rather than a rule — a whole chart has far more to say about two people than their sun signs do.
