September 27 zodiac sign: Libra, first decan

If you were born on September 27, your sign is Libra, the air sign ruled by Venus: the Sun is in Libra on this date in every year from 1980 to 2030. The Sun sits about 4° into Libra on this date, in the first decan, where Libra's core takes on a Moon flavour. Here's what the date fixes, and what only your birth time can tell you.

Your sign: Libra

The cardinal air sign that lives in relationship and refuses to choose between two goods.

A Libra Sun is built around fairness and the relational fabric. You're allergic to bullies and to anyone who treats other people as means rather than ends. You see all sides — the gift and the curse of your sign — and you're often the person who can name what each side actually wants when everyone else has lost the thread.

The date fixes the Sun; the year and hour fix the rest. A Libra born September 27 with the Moon in Libra runs on a different inner weather from one with the Moon in Libra: see Libra Sun, Libra Moon. Your rising sign needs the birth time; the twelve Libra Sun combinations show what each one changes.

In the US (2000–2014), an average of 12,172 babies were born on each September 27, rank 27 of 366 dates; Libra is number 5 of 12 signs (8.52%). What's the most common zodiac sign?

The Moon on September 27, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on September 27 was most often in Taurus and Libra (6 years each) and least often in Cancer, Sagittarius, and Aquarius (3 years each). Unlike the Sun, the Moon sign depends on the birth year. On September 27, 2026, the Moon stays in Aries the whole UTC day.

In 24 of those 51 years (47%) the Moon changed sign during September 27 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 September 27 in 1996, and new in 2000, 2011, and 2030.

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 first decan of Libra

Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 0–10 of Libra 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 Libra 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 Libras born on September 27 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 September 27?

What decan is September 27?

The first decan of Libra (0°–10°), 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 September 27?

In the Golden Dawn system each decan has a minor arcana card: for the first decan of Libra it is the Two of Swords (stalemate, difficult choice, truce). 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 September 27?

It depends on the year, and in 47% of years on the hour too. For example: in 1980, Taurus; in 1990, Capricorn; in 2000, Virgo or Libra; in 2010, Taurus; in 2020, Aquarius. Over 1980–2030 the Moon on September 27 was most often in Taurus and Libra. A birth time and place pin it down.

Does everyone born on September 27 have the same chart?

No. They share the Sun in Libra, 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 September 27 in different years can have almost nothing else in common in their charts.
