Born on September 23
A cusp birthday. In most years the Sun crosses from Virgo into Libra during September 23, so people born this day are one or the other depending on the hour. At noon UTC it's Libra in 92% of years.
Virgo or Libra? Check your year
The Sun's entry into Libra shifts by a few hours from year to year. Find your birth year, convert your birth time to UTC, and compare: born before the time shown, you're Virgo; after it, Libra. Years missing from the list had the crossing on a neighbouring day (the Sun was in one sign for the whole of September 23).
Not sure about the time zone or the minutes? Compute your chart — it does the conversion and settles the sign.
Your sign: Libra (or Virgo)
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.

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.
Two of Swords
Stalemate · Difficult choice · Truce. 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 Libras born on September 23 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
Is September 23 Virgo or Libra?
Both are possible. On September 23 the Sun moves from Virgo into Libra in most years, at a time that ranges from 00:05 UTC to 14:41 UTC UTC across 1980–2030 (in some years the crossing falls on the neighbouring day). Convert your birth time to UTC and compare it with the crossing for your year in the table above — before it you're Virgo, after it Libra.
What zodiac sign is September 23?
September 23 is a cusp day between Virgo and Libra; at noon UTC it falls in Libra in 92% of years between 1980 and 2030. Your birth year and hour decide it.
What decan is September 23?
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 23?
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.
Does everyone born on September 23 have the same chart?
No. They share the Sun in Libra or Virgo, 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 23 in different years can have almost nothing else in common in their charts.
