October 12 zodiac sign: Libra, second decan

If you were born on October 12, 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 19° into Libra on this date, in the second decan, where Libra's core takes on a Saturn 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 hour fixes the rest. A Libra born October 12 in the small hours has Leo rising, and a different first impression from one born at dawn. 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 11,267 babies were born on each October 12, rank 203 of 366 dates; Libra is number 5 of 12 signs (8.52%). What's the most common zodiac sign?

The Moon on October 12, 1980–2030

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

In 22 of those 51 years (43%) the Moon changed sign during October 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 October 12 in 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 Libra

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 Libra belong to Saturn: where you face limitation and, through facing it, build mastery. Read it as Libra with a Saturn accent — the air core is unchanged, the emphasis moves.

October 12 sits on a decan boundary: in 6 of the 51 years from 1980 to 2030 the Sun spends part or all of the day (UTC) in the third decan of Libra (20°–30°), sub-ruled by Jupiter. 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 Libras born on October 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.

What decan is October 12?

The second decan of Libra (10°–20°), sub-ruled by Saturn. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here where you face limitation and, through facing it, build mastery.

What tarot card is October 12?

In the Golden Dawn system each decan has a minor arcana card: for the second decan of Libra it is the Three of Swords (heartbreak, grief, painful truth). 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 October 12?

It depends on the year, and in 43% of years on the hour too. For example: in 1980, Scorpio or Sagittarius; in 1990, Cancer or Leo; in 2000, Aries; in 2010, Sagittarius; in 2020, Leo. Over 1980–2030 the Moon on October 12 was most often in Leo. A birth time and place pin it down.

Does everyone born on October 12 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 October 12 in different years can have almost nothing else in common in their charts.
