Capricorn decans

Capricorn spans 30 degrees, and astrologers traditionally divide every sign into three 10-degree decans. It is where the “December Capricorn” versus “January Capricorn” 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.

FirstDecember 22 – December 31

Capricorn Man

The Capricorn man earns trust slowly and spends it carefully. Cardinal earth, Saturn-ruled — that combination produces someone who is genuinely interested in building things that last, whether that's a career, a reputation, or a Saturday morning routine he has followed for six years. At a dinner party he's the one who listens more than he talks, asks a pointed question late in the evening, and somehow leaves with everyone's respect without having tried very hard for it. He is not cold, though he reads that way at first. He is just measuring. Pile pressure on him and he gets quieter, more methodical; he does not scatter. The frustrating part, honestly, is that he can mistake caution for wisdom and drag his feet long after the moment has passed. He's better in the long game than the short one, and he knows it.

Capricorn Woman

The Capricorn woman has usually already solved the problem before anyone else has finished describing it. She's Dec 22 - Jan 19, cardinal earth, and that cardinalness matters — she initiates, she structures, she would rather be the one who set the plan in motion than the one who reacts to someone else's. Saturn's influence shows up as a particular kind of patience: she will wait out almost any difficulty as long as she can see a reason to. In a disagreement she doesn't raise her voice; she gets precise, which can be more unsettling. She tends to carry responsibility the way other people carry a phone — constantly, reflexively, without thinking to put it down. The ambition is real but it's rarely loud. She'd rather show you the finished result than describe what she's working toward.

The earth signs

Capricorn shares the earth element with Taurus and Virgo. 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

Capricorn is cardinal, alongside Aries, Cancer and Libra. 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

Earth and water signs are traditionally described as compatible with each other, which puts Capricorn alongside the water 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.
