December 6 zodiac sign: Sagittarius, second decan
If you were born on December 6, your sign is Sagittarius, the fire sign ruled by Jupiter: the Sun is in Sagittarius on this date in every year from 1980 to 2030. The Sun sits about 14° into Sagittarius on this date, 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.

The date fixes the Sun; the year and hour fix the rest. A Sagittarius born December 6 with the Moon in Libra runs on a different inner weather from one with the Moon in Sagittarius: see Sagittarius Sun, Libra Moon. Your rising sign needs the birth time; the twelve Sagittarius Sun combinations show what each one changes.

In 23 of those 51 years (45%) the Moon changed sign during December 6 itself, so in those years the birth time decides the Moon as well as the rising sign. Cells with an arrow mark them, with the UTC time of the change. The Moon was exactly full on December 6 in 2014, and new in 1991.
Find your birth year. One sign means the Moon spent the whole UTC day there; an arrow means it changed sign that day, at the UTC time shown: born before it, the first sign; after it, the second. The Moon sign calculator settles it in seconds; your birth chart adds the rising sign and houses.
Times in UTC: a birth late in the evening in the Americas, or early in the morning in Asia, can fall on the neighbouring UTC date.

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.

What the date can't tell you
The Sun is one placement out of ten. Your Moon sign changes every two to three days, so Sagittarians born on December 6 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 6?
December 6 is Sagittarius, the mutable fire sign ruled by Jupiter. The Sun sits at roughly 14° Sagittarius on this date, in the second decan.
What decan is December 6?
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 6?
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.
What Moon sign is someone born on December 6?
It depends on the year, and in 45% of years on the hour too. For example: in 1980, Scorpio or Sagittarius; in 1990, Leo; in 2000, Aries; in 2010, Sagittarius or Capricorn; in 2020, Leo or Virgo. Over 1980–2030 the Moon on December 6 was most often in Leo. A birth time and place pin it down.
Does everyone born on December 6 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 6 in different years can have almost nothing else in common in their charts.
