♒︎ Sun at ~24° Aquarius · third decan · Moon

February 13 zodiac sign: Aquarius, third decan

If you were born on February 13, your sign is Aquarius, the air sign ruled by Uranus: the Sun is in Aquarius on this date in every year from 1980 to 2030. The Sun sits about 24° into Aquarius on this date, in the third decan, where Aquarius's core takes on a Moon flavour. Here's what the date fixes, and what only your birth time can tell you.

Your sign: Aquarius

The fixed air sign that thinks in systems and refuses to inherit its opinions.

An Aquarius Sun is built around originality and systemic thinking. You don't take "this is how it's done" as a sufficient reason for anything. You ask why, and if the answer is just tradition, you're free to do something different. This makes you a natural innovator, an effective dissident, and an occasional pain in the ass to people who like consensus.

The date fixes the Sun; the hour fixes the rest. A Aquarius born February 13 in the late evening has Libra rising, and a different first impression from one born at dawn. Your rising sign needs the birth time; the twelve Aquarius Sun combinations show what each one changes.

In the US (2000–2014), an average of 10,864 babies were born on each February 13, rank 325 of 366 dates; Aquarius is number 11 of 12 signs (7.93%). What's the most common zodiac sign?

The Moon on February 13, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on February 13 was most often in Gemini (7 years) and least often in Cancer, Virgo, and Pisces (3 years each). Unlike the Sun, the Moon sign depends on the birth year. On February 13, 2026, the Moon stays in Capricorn the whole UTC day.

In 22 of those 51 years (43%) the Moon changed sign during February 13 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 February 13 in 1987 and 2006, and new in 1983 and 2029.

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 third decan of Aquarius

Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 20–30 of Aquarius 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 Aquarius with a Moon accent — the air 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 Aquarians born on February 13 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 February 13?

February 13 is Aquarius, the fixed air sign ruled by Uranus. The Sun sits at roughly 24° Aquarius on this date, in the third decan.

What decan is February 13?

The third decan of Aquarius (20°–30°), 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 February 13?

In the Golden Dawn system each decan has a minor arcana card: for the third decan of Aquarius it is the Seven of Swords (strategy, stealth, evasion). 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 February 13?

It depends on the year, and in 43% of years on the hour too. For example: in 1980, Capricorn; in 1990, Libra; in 2000, Taurus or Gemini; in 2010, Aquarius; in 2020, Libra. Over 1980–2030 the Moon on February 13 was most often in Gemini. A birth time and place pin it down.

Does everyone born on February 13 have the same chart?

No. They share the Sun in Aquarius, 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 February 13 in different years can have almost nothing else in common in their charts.
