♈︎ Sun at ~23° Aries · third decan · Venus

April 13 zodiac sign: Aries, third decan

If you were born on April 13, your sign is Aries, the fire sign ruled by Mars: the Sun is in Aries on this date in every year from 1980 to 2030. The Sun sits about 23° into Aries on this date, in the third decan, where Aries's core takes on a Venus flavour. Here's what the date fixes, and what only your birth time can tell you.

Your sign: Aries

The first sign of the zodiac — initiator, fighter, and patron of fresh starts.

If your Sun is in Aries, your core identity is built around action. You feel most yourself when you're starting something — a project, a fight, a workout, a brand-new chapter. You hate stagnation more than you hate failure. The slow consensus-building meetings and the relationships that need careful tending? That's not where you shine. You shine in the opening move, the new venture, the moment someone needs to just decide already.

The date fixes the Sun; the hour fixes the rest. A Aries born April 13 in the late evening has Sagittarius rising, and a different first impression from one born at dawn. Your rising sign needs the birth time; the twelve Aries Sun combinations show what each one changes.

In the US (2000–2014), an average of 10,501 babies were born on each April 13, rank 349 of 366 dates; Aries is number 8 of 12 signs (8.14%). What's the most common zodiac sign?

The Moon on April 13, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on April 13 was most often in Leo (6 years) and least often in Scorpio (2 years). Unlike the Sun, the Moon sign depends on the birth year. On April 13, 2026, the Moon moves from Aquarius into Pisces at 08:55 UTC.

In 22 of those 51 years (43%) the Moon changed sign during April 13 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 April 13 in 2006 and 2025, and new in 1983 and 2029.

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 Aries

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 Aries belong to Venus: how you love, what you find beautiful, and what you value. Read it as Aries with a Venus accent — the fire 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 Aries born on April 13 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 April 13?

April 13 is Aries, the cardinal fire sign ruled by Mars. The Sun sits at roughly 23° Aries on this date, in the third decan.

What decan is April 13?

The third decan of Aries (20°–30°), sub-ruled by Venus. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here how you love, what you find beautiful, and what you value.

What tarot card is April 13?

In the Golden Dawn system each decan has a minor arcana card: for the third decan of Aries it is the Four of Wands (celebration, homecoming, harmony). 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 April 13?

It depends on the year, and in 43% of years on the hour too. For example: in 1980, Pisces or Aries; in 1990, Scorpio or Sagittarius; in 2000, Leo; in 2010, Aries; in 2020, Sagittarius or Capricorn. Over 1980–2030 the Moon on April 13 was most often in Leo. A birth time and place pin it down.

Does everyone born on April 13 have the same chart?

No. They share the Sun in Aries, 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 April 13 in different years can have almost nothing else in common in their charts.
