Born on December 7
Your Sun is in Sagittarius, about 15° in — the second decan, where Sagittarius's core takes on a Moon flavour. Here's what the date fixes, and what only your birth time can tell you.
Your sign: Sagittarius
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.

Your decan: the second decan of Sagittarius
Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 10–20 of Sagittarius belong to Moon: your inner emotional life — what you need to feel safe, how you self-soothe, how you love and are loved. Read it as Sagittarius with a Moon accent — the fire core is unchanged, the emphasis moves.
Nine of Wands
Resilience · Boundaries · Last stand. The card assigned to this ten-degree slice of the zodiac — a birthday card in the same sense a sun sign is a birthday sign: one lens on the date, not a verdict.

The Sun is one placement out of ten. Your Moon sign changes every two to three days, so Sagittarians born on December 7 in different years have different Moons; your rising sign changes every two hours and needs a birth time and place. Those two carry most of what people mean by "personality" in a chart.

Common questions
What zodiac sign is December 7?
December 7 is Sagittarius, the mutable fire sign ruled by Jupiter. The Sun sits at roughly 15° Sagittarius on this date, in the second decan.
What decan is December 7?
The second decan of Sagittarius (10°–20°), sub-ruled by Moon. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here your inner emotional life — what you need to feel safe, how you self-soothe, how you love and are loved.
What tarot card is December 7?
In the Golden Dawn system each decan has a minor arcana card: for the second decan of Sagittarius it is the Nine of Wands (resilience, boundaries, last stand). It's a birthday card in the same way a sun sign is — one lens, not a verdict.
Does everyone born on December 7 have the same chart?
No. They share the Sun in Sagittarius, but the Moon changes sign every two to three days, the rising sign every two hours, and the outer planets by year. Two people born December 7 in different years can have almost nothing else in common in their charts.
