September 12 zodiac sign: Virgo, second decan

If you were born on September 12, your sign is Virgo, the earth sign ruled by Mercury: the Sun is in Virgo on this date in every year from 1980 to 2030. The Sun sits about 19° into Virgo on this date, in the second decan, where Virgo's core takes on a Venus flavour. Here's what the date fixes, and what only your birth time can tell you.

Your sign: Virgo

The mutable earth sign that notices everything and refines until it works.

A Virgo Sun has an analytical mind paired with a service orientation — a rare combination. You're the person who actually reads the manual, who notices what's off in the system, who stays late to make sure the thing works the way it's supposed to. You're not loud about it. You just do the work.

The date fixes the Sun; the hour fixes the rest. A Virgo born September 12 in the early afternoon has Capricorn rising, and a different first impression from one born at dawn. Your rising sign needs the birth time; the twelve Virgo Sun combinations show what each one changes.

In the US (2000–2014), an average of 12,735 babies were born on each September 12, rank 1 of 366 dates; Virgo is number 2 of 12 signs (8.94%). What's the most common zodiac sign?

The Moon on September 12, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on September 12 was most often in Libra (6 years) and least often in Virgo (2 years). Unlike the Sun, the Moon sign depends on the birth year. On September 12, 2026, the Moon stays in Libra the whole UTC day.

In 25 of those 51 years (49%) the Moon changed sign during September 12 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 12 in 1992 and 2011, and new in 1996.

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 Virgo

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 Virgo belong to Venus: how you love, what you find beautiful, and what you value. Read it as Virgo with a Venus accent — the earth core is unchanged, the emphasis moves.

September 12 sits on a decan boundary: in 36 of the 51 years from 1980 to 2030 the Sun spends part or all of the day (UTC) in the third decan of Virgo (20°–30°), sub-ruled by Mercury. 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 Virgos born on September 12 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.

In the Golden Dawn system each decan has a minor arcana card: for the second decan of Virgo it is the Nine of Pentacles (independence, refinement, self-sufficiency). 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 12?

It depends on the year, and in 49% of years on the hour too. For example: in 1980, Libra; in 1990, Gemini or Cancer; in 2000, Aquarius or Pisces; in 2010, Scorpio; in 2020, Cancer. Over 1980–2030 the Moon on September 12 was most often in Libra. A birth time and place pin it down.

Does everyone born on September 12 have the same chart?

No. They share the Sun in 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 12 in different years can have almost nothing else in common in their charts.
