♓︎ Sun at ~21° Pisces · third decan · Mars

March 12 zodiac sign: Pisces, third decan

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

Your sign: Pisces

The mutable water sign that dissolves boundaries and feels what others don't even notice.

A Pisces Sun is built around empathy and imagination. You feel things that haven't been said. You read the room, the energy, the unspoken — and you're often right. This intuition is real, and it makes you formidable in any creative or healing field that rewards seeing what's beneath the surface.

The date fixes the Sun; the hour fixes the rest. A Pisces born March 12 around sunrise has Pisces rising, and a different first impression from one born at dawn. Your rising sign needs the birth time; the twelve Pisces Sun combinations show what each one changes.

In the US (2000–2014), an average of 11,204 babies were born on each March 12, rank 228 of 366 dates; Pisces is number 9 of 12 signs (8.04%). What's the most common zodiac sign?

The Moon on March 12, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on March 12 was most often in Taurus (6 years) and least often in Leo, Virgo, and Pisces (3 years each). Unlike the Sun, the Moon sign depends on the birth year. On March 12, 2026, the Moon moves from Sagittarius into Capricorn at 04:07 UTC.

In 24 of those 51 years (47%) the Moon changed sign during March 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 March 12 in 2017, and new in 1994.

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 Pisces

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 Pisces belong to Mars: your drive — how you take action, what makes you angry, and what you fight for. Read it as Pisces with a Mars accent — the water 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 Pisceans born on March 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 March 12?

March 12 is Pisces, the mutable water sign ruled by Neptune. The Sun sits at roughly 21° Pisces on this date, in the third decan.

What decan is March 12?

The third decan of Pisces (20°–30°), sub-ruled by Mars. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here your drive — how you take action, what makes you angry, and what you fight for.

What tarot card is March 12?

In the Golden Dawn system each decan has a minor arcana card: for the third decan of Pisces it is the Ten of Cups (harmony, family joy, fulfilment). 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 March 12?

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

Does everyone born on March 12 have the same chart?

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