December zodiac signs
December belongs to two signs: Sagittarius first, then Capricorn. In 2026 the Sun makes the crossing on December 21 at 20:50 UTC. Pick your day for the sign, the decan, the tarot card, and — on cusp days — the exact hour for your birth year.
Sagittarius in December
The mutable fire sign that aims at the bigger picture and refuses to be domesticated.
A Sagittarius Sun is built around expansion and meaning. You're the friend who has lived in three countries, who keeps reading philosophy at 2am, who wants to know what people actually think rather than what they're supposed to say. Your optimism is real — not the brittle "everything happens for a reason" kind, but a genuine sense that life is interesting and worth showing up for.
Capricorn in December
The cardinal earth sign that plays the long game and refuses to be flashy about it.
A Capricorn Sun is built around discipline and long-term thinking. You're the friend who actually executed on the plan everyone else was just talking about. You don't need praise for doing what you said you'd do — that's just baseline integrity to you. People often underestimate Capricorns at twenty-five and overestimate everyone else; by forty, the curve catches up, and the people who took you for slow find out you were just consistent.
