August 31 zodiac sign: Virgo, first decan

If you were born on August 31, 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 8° into Virgo on this date, in the first decan, where Virgo's core takes on a Sun 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 August 31 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 11,825 babies were born on each August 31, rank 73 of 366 dates; Virgo is number 2 of 12 signs (8.94%). What's the most common zodiac sign?

The Moon on August 31, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on August 31 was most often in Libra (7 years) and least often in Cancer, Sagittarius, and Capricorn (3 years each). Unlike the Sun, the Moon sign depends on the birth year. On August 31, 2026, the Moon stays in Aries the whole UTC day.

In 22 of those 51 years (43%) the Moon changed sign during August 31 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 August 31 in 2012 and 2023, and new in 1989 and 2027.

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 first 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 0–10 of Virgo belong to Sun: the core of who you are — your conscious identity, your will, your essential self. Read it as Virgo with a Sun accent — the earth 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 Virgos born on August 31 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 August 31?

August 31 is Virgo, the mutable earth sign ruled by Mercury. The Sun sits at roughly 8° Virgo on this date, in the first decan.

What decan is August 31?

The first decan of Virgo (0°–10°), 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 August 31?

In the Golden Dawn system each decan has a minor arcana card: for the first decan of Virgo it is the Eight of Pentacles (skill, diligence, mastery). 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 August 31?

It depends on the year, and in 43% of years on the hour too. For example: in 1980, Taurus; in 1990, Capricorn; in 2000, Virgo or Libra; in 2010, Taurus; in 2020, Aquarius. Over 1980–2030 the Moon on August 31 was most often in Libra. A birth time and place pin it down.

Does everyone born on August 31 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 August 31 in different years can have almost nothing else in common in their charts.
