Leo is the fifth sign of the zodiac, covering everyone born between July 23 and August 22 — a window that, like Gemini’s, straddles two separate birthstone months, which is why the honest answer to “what’s the Leo stone” has more than one part. Leo is ruled by the Sun, carries the fixed fire element, and takes its symbol from the lion. This guide covers Leo’s real dates, where the lion symbol comes from, the sign’s actual personality reputation, its traditional zodiac stone versus its calendar birthstones, and what that means if you’re buying jewelry for a Leo.

Leo Dates, Element, and Ruling Planet

Leo runs from July 23 to August 22 in most modern tropical-zodiac calendars, following Cancer and opening the second half of summer. Its element is fire, shared with Aries and Sagittarius, and its modality is fixed — the middle sign of each season, associated with sustaining and stabilizing rather than starting or ending a cycle.

Its ruling planet is the Sun, which makes Leo the only sign not ruled by one of the other planets or by the Moon. That placement is the traditional source for Leo’s association with confidence, visibility, and warmth — the sign is described as the zodiac’s center of attention in the same way the Sun sits at the center of the solar system.

In plain terms: a Leo birthday falls in the last nine days of July or the first three weeks of August — there’s no Leo birthday outside July 23 through August 22, and no version of the sign born in any other month. For the full rundown of how Leo fits alongside the other eleven signs — dates, elements, and ruling planets side by side — see our zodiac signs by month guide.

The Lion: Where the Leo Symbol Comes From

Leo takes its symbol, and its Latin name for “lion,” from the Nemean Lion of Greek myth — a beast with a hide no weapon could pierce, terrorizing the region around Nemea until Hercules was sent to kill it as the first of his twelve labors. Unable to pierce the lion’s skin with arrows or a sword, Hercules strangled it barehanded, then used one of its own claws to skin it, wearing the pelt afterward as armor.

In the most common version of the myth, Zeus (or in some tellings Hera) placed the lion among the stars afterward to commemorate the labor, giving the constellation — and the zodiac sign that shares its dates — its name and its association with strength and dominance.

Leo Personality Traits, Honestly

As with any sign, Leo’s personality reputation comes from a centuries-old descriptive tradition, not measurable data, and it’s worth reading it that way. The recurring traits attached to Leo are confidence, generosity, and warmth — a sign described as naturally comfortable leading a room and quick to encourage the people in it, tied back to the Sun’s role as the thing everything else orbits.

The same traits read as strengths or flaws depending on framing: a taste for recognition and a need for an audience are, structurally, the same trait — wanting what you do to be seen and valued. The sign’s fixed modality is described the same double-edged way: loyalty and consistency on one hand, stubbornness and a resistance to being told what to do on the other.

Leo's Traditional Stone vs. Its Birthstone

Sources differ here more than for most signs. Peridot is the most consistently cited traditional zodiac stone for Leo in older gem-lore compilations, though a few sources cite ruby or onyx instead — there is no single agreed-on “real” Leo stone the way there is for some other signs.

Because Leo spans July 23 to August 22, it crosses two birthstone months: ruby for anyone born in the July portion, and peridot (or spinel, added as a second official August birthstone in 2016) for anyone born from August 1 onward — two stones with almost nothing in common, one a deep red corundum, the other a pale olive-green silicate.

If you’re buying by the calendar date on a birth certificate, the birthstone is the traditional choice. If you’re buying by star sign specifically — someone who identifies strongly as a Leo regardless of which half of the window they were born in — peridot is the safer default, since it’s the stone actually cited as “Leo’s” most often. A birthstone necklace lets you sidestep the question entirely by matching the stone to the exact birth date instead of the sign.

Leo Compatibility

Compatibility astrology is built more around element and modality than any single trait. Leo, a fixed fire sign, is most often described as compatible with the other fire signs, Aries and Sagittarius, and with the air signs — Gemini, Libra, and Aquarius — whose element is traditionally said to feed fire rather than compete with it.

The pairings flagged as harder are the other fixed signs — Taurus, Scorpio, and Aquarius — where two temperaments that each resist changing course can end up locked in a standoff neither side backs down from first. None of this is predictive in any measurable sense; it’s a centuries-old descriptive framework, not a compatibility test with evidence behind it.

Jewelry and Gifts for a Leo

Given Leo’s reputation for confidence and a taste for being noticed, gifts for the sign tend to land best when they’re a genuine statement rather than something quiet and easy to overlook — a bolder personalized ring reads as more “Leo” than a piece meant to blend in.

For something tied to an actual birth date rather than the sign itself, a birthstone necklace lets you match the birthstone to the day, in ruby or peridot depending on where in the Leo window the birthday falls.

Frequently Asked Questions

What are the exact dates for Leo?

Leo runs from July 23 to August 22 in most modern tropical-zodiac calendars, though the exact start and end can shift by a day depending on the year, since the zodiac follows the solar calendar rather than a fixed calendar date.

What is Leo's ruling planet?

The Sun. Leo is the only sign ruled by the Sun rather than by a planet or the Moon, which is the traditional source for its association with confidence, visibility, and being the center of attention.

What is Leo's real stone — peridot, ruby, or onyx?

All three show up depending on the source. Peridot is the most consistently cited traditional zodiac stone for Leo. Ruby and spinel are the calendar birthstones for the two months Leo spans — ruby for late July, peridot or spinel for August — so which one is “right” depends on whether you’re buying by sign or by birth date.

Is Leo a fire sign or a fixed sign?

Both — the two describe different things. Fire is Leo's element, shared with Aries and Sagittarius. Fixed is its modality, shared with Taurus, Scorpio, and Aquarius, describing its tendency to sustain and stabilize rather than start or end a cycle.

What's the mythological origin of the Leo symbol?

The Nemean Lion, an invulnerable-skinned beast that Hercules killed barehanded as the first of his twelve labors, after arrows and swords failed to pierce its hide. Zeus (or, in some versions, Hera) is credited with placing the lion among the stars afterward, giving the constellation its name.
