July 31 zodiac sign: Leo, first decan

If you were born on July 31, your sign is Leo, the fire sign ruled by Sun: the Sun is in Leo on this date in every year from 1980 to 2030. The Sun sits about 8° into Leo on this date, in the first decan, where Leo's core takes on a Saturn flavour. Here's what the date fixes, and what only your birth time can tell you.

Your sign: Leo

The fixed fire sign that brings warmth and refuses to be small.

A Leo Sun puts the Sun in its own sign — your core identity is amplified, radiant, and visible. You generate energy that other people warm themselves on. The friend whose laugh fills the room, the colleague who turns a project into something people are proud to be part of, the host who makes a dinner party an actual event — that's you, in your element.

The date fixes the Sun; the year and hour fix the rest. A Leo born July 31 with the Moon in Libra runs on a different inner weather from one with the Moon in Leo: see Leo Sun, Libra Moon. Your rising sign needs the birth time; the twelve Leo Sun combinations show what each one changes.

In the US (2000–2014), an average of 11,812 babies were born on each July 31, rank 75 of 366 dates; Leo is number 1 of 12 signs (8.96%). What's the most common zodiac sign?

The Moon on July 31, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on July 31 was most often in Cancer, Virgo, and Aquarius (6 years each) and least often in Taurus, Gemini, Libra, and Scorpio (3 years each). Unlike the Sun, the Moon sign depends on the birth year. On July 31, 2026, the Moon moves from Aquarius into Pisces at 12:14 UTC.

In 20 of those 51 years (39%) the Moon changed sign during July 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 July 31 in 1985, 2004, and 2015, and new in 1981 and 2000.

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 Leo

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 Leo belong to Saturn: where you face limitation and, through facing it, build mastery. Read it as Leo with a Saturn 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 Leos born on July 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 July 31?

July 31 is Leo, the fixed fire sign ruled by Sun. The Sun sits at roughly 8° Leo on this date, in the first decan.

What decan is July 31?

The first decan of Leo (0°–10°), 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 July 31?

In the Golden Dawn system each decan has a minor arcana card: for the first decan of Leo it is the Five of Wands (competition, conflict, tension). 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 July 31?

It depends on the year, and in 39% 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 July 31 was most often in Cancer, Virgo, and Aquarius. A birth time and place pin it down.

Does everyone born on July 31 have the same chart?

No. They share the Sun in Leo, 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 July 31 in different years can have almost nothing else in common in their charts.
