December 11 zodiac sign: Sagittarius, second decan

If you were born on December 11, 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 19° 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 hour fixes the rest. A Sagittarius born December 11 in the small hours has Libra rising, and a different first impression from one born at dawn. Your rising sign needs the birth time; the twelve Sagittarius Sun combinations show what each one changes.

In the US (2000–2014), an average of 11,252 babies were born on each December 11, rank 210 of 366 dates; Sagittarius is number 10 of 12 signs (7.95%). What's the most common zodiac sign?

The Moon on December 11, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on December 11 was most often in Gemini (6 years) and least often in Taurus, Leo, and Virgo (3 years each). Unlike the Sun, the Moon sign depends on the birth year. On December 11, 2026, the Moon stays in Capricorn the whole UTC day.

In 22 of those 51 years (43%) the Moon changed sign during December 11 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 11 in 1981 and 2000, and new in 2015.

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.

December 11 sits on a decan boundary: in 21 of the 51 years from 1980 to 2030 the Sun spends part or all of the day (UTC) in the third decan of Sagittarius (20°–30°), sub-ruled by Saturn. Which one is yours depends on your birth year and time; a birth chart gives the exact degree.

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 11 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.

What decan is December 11?

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.

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 11?

It depends on the year, and in 43% of years on the hour too. For example: in 1980, Capricorn or Aquarius; in 1990, Libra; in 2000, Gemini; in 2010, Aquarius or Pisces; in 2020, Libra or Scorpio. Over 1980–2030 the Moon on December 11 was most often in Gemini. A birth time and place pin it down.

Does everyone born on December 11 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 11 in different years can have almost nothing else in common in their charts.
