June 12 zodiac sign: Gemini, third decan

If you were born on June 12, your sign is Gemini, the air sign ruled by Mercury: the Sun is in Gemini on this date in every year from 1980 to 2030. The Sun sits about 21° into Gemini on this date, in the third decan, where Gemini's core takes on a Sun flavour. Here's what the date fixes, and what only your birth time can tell you.

Your sign: Gemini

The mutable air sign that lives by language — quick to learn, quick to pivot, quick to bore.

A Gemini Sun makes a mind that genuinely runs faster than most. You learn quickly, talk quickly, and link ideas across domains in a way that surprises specialists. Your gift is the connection — between two unrelated fields, between two people who'd never meet without you, between an old idea and a new use for it. You're a natural translator.

The date fixes the Sun; the hour fixes the rest. A Gemini born June 12 in the late evening has Aquarius rising, and a different first impression from one born at dawn. Your rising sign needs the birth time; the twelve Gemini Sun combinations show what each one changes.

In the US (2000–2014), an average of 11,518 babies were born on each June 12, rank 135 of 366 dates; Gemini is number 4 of 12 signs (8.56%). What's the most common zodiac sign?

The Moon on June 12, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on June 12 was most often in Gemini and Scorpio (6 years each) and least often in Leo, Virgo, and Pisces (3 years each). Unlike the Sun, the Moon sign depends on the birth year. On June 12, 2026, the Moon stays in Taurus the whole UTC day.

In 24 of those 51 years (47%) the Moon changed sign during June 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 new on June 12 in 1980, 1991, 2010, and 2029; it was never full on this date between 1980 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 third decan of Gemini

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 Gemini belong to Sun: the core of who you are — your conscious identity, your will, your essential self. Read it as Gemini with a Sun 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 Geminis born on June 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.

Common questions

What zodiac sign is June 12?

June 12 is Gemini, the mutable air sign ruled by Mercury. The Sun sits at roughly 21° Gemini on this date, in the third decan.

What decan is June 12?

The third decan of Gemini (20°–30°), sub-ruled by Sun. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here the core of who you are — your conscious identity, your will, your essential self.

What tarot card is June 12?

In the Golden Dawn system each decan has a minor arcana card: for the third decan of Gemini it is the Ten of Swords (ending, rock bottom, release). 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 June 12?

It depends on the year, and in 47% of years on the hour too. For example: in 1980, Gemini; in 1990, Aquarius; in 2000, Libra or Scorpio; in 2010, Gemini; in 2020, Pisces. Over 1980–2030 the Moon on June 12 was most often in Gemini and Scorpio. A birth time and place pin it down.

Does everyone born on June 12 have the same chart?

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