Leo is the fifth sign of the tropical zodiac. A fixed Fire sign set in the heart of summer, it is the only sign in the zodiac ruled by the Sun itself, which makes it a case apart in the whole astrological tradition. This page covers Leo in detail: its exact dates, its place in the sky, its element, its planetary ruler, its mythological symbolism, its archetypal traits, and how to read the sign depending on whether Leo is your Sun, your Moon or your Rising sign. You will also find notes on Leo compatibility, on the tropical versus sidereal question, and a FAQ.

Leo dates: July 23 to August 22 (tropical)

In tropical astrology (the reference system of modern Western astrology), the Sun enters Leo around July 23 and leaves it around August 22. The dates shift slightly from year to year: the entry can land on July 22 or 23, the exit on August 22 or 23. For 2026, check a current-year ephemeris or the Astrolabica interactive chart for the exact date and time.

Having your Leo Sun sign means being born inside that window. But as with every sign, your Sun sign is only one facet of the chart. The Moon in Leo, a Leo Rising, or several planets in Leo count just as much, sometimes more, depending on the configuration.

⚠️ One thing to note: if you use a sidereal astrology system (Indian astrology, or some Western astrologers), the dates are different. The Sun enters sidereal Leo about 24 days later, around August 17. This shift, caused by the precession of the equinoxes, is explained in full in Tropical vs sidereal.

Leo in the sky: astronomical position

The constellation Leo is one of the most recognizable in the northern sky. Its shape, a backwards sickle (often called "the Sickle" or "the lion's head"), is visible to the naked eye under a clear sky from temperate latitudes, between spring and early summer.

Its main star, Regulus (α Leonis), carries a Latin name meaning "the little king": regulus is the diminutive of rex. It is one of the four royal stars of the Mesopotamian and Persian tradition. Regulus sits almost exactly on the ecliptic, which means the Moon and the planets often appear to pass close to it. In astrology, Regulus is one of the most active fixed stars in chart interpretation.

In tropical astrology, the constellation Leo occupies the sector from 120° to 150° of the zodiac measured from the vernal point. Those 30 degrees of ecliptic define the sign symbolically, regardless of where the stars actually sit today. For how this mechanism works, see The astrological sky: the astronomical basics.

The Leo glyph ♌ stylizes the mane and tail of the animal, a line that also suggests the winding shape of a vital impulse. Some authors even read it as a reference to the spermatozoon, tying into the themes of creativity and generated life (consistent with the sign's natural 5th house).

Element, mode, polarity: the Leo signature

Every sign carries a combination of three core attributes.

Fire: the element

Leo is a Fire sign, like Aries and Sagittarius. Fire signs share enthusiasm, drive, radiance and direct expression. Yet Fire shows up differently in each of them.

Aries burns fast and hard: it is the spark. Sagittarius burns in service of a vision or a horizon, a fire that lights the road ahead. Leo burns steadily and theatrically: it is the hearth, the flame you keep tending.

Leo's Fire is sustained and continuous. A luminous presence, a radiating warmth, a capacity to light up the space around it in a lasting way rather than in bursts.

Fixed: the mode

Leo is a fixed sign, like Taurus, Scorpio and Aquarius. Fixed signs arrive in the middle of a season (Leo, at the peak of summer) and they go with consolidation: holding, maintaining, deepening, stabilizing.

Cardinal signs (Aries, Cancer, Libra, Capricorn) initiate. Mutable signs (Gemini, Virgo, Sagittarius, Pisces) transform. Fixed signs hold on, and sometimes they never let go.

In Leo, that fixed mode shows up concretely as bulletproof loyalty toward what it believes in, tenacity in creative projects, and resistance to changes it did not set in motion itself. The friction point: a real difficulty in questioning itself when the ego is on the line.

Positive / yang: the polarity

Leo is a positive sign (or yang, or masculine in the classical terminology, all of these terms being symbolic, not gendered). Its energy is outgoing: turned toward the outside, toward expression, toward impact on the world. With Fire plus Fixed plus Yang, the archetype is structurally pointed at one thing: shining outward, durably and assertively.

The Sun: Leo's planetary ruler

Leo's planetary ruler is the Sun, which makes it the only sign in the zodiac governed by our star. Every other sign is ruled by a planet. Leo goes straight back to the light source of the solar system.

This Sun-Leo bond matters enormously: the Sun is in domicile in Leo, meaning it expresses its energy here in the most direct and fluid way. The Leo archetype carries every solar quality within it: radiance, centrality, conscious identity, vitality, generosity, sovereignty.

The Sun in domicile in Leo is one of the placements considered among the "purest" in a chart. Not "best", but undiluted: the Sun speaks with no intermediate planetary filter.

To understand the Sun as an astrological planet, see The Sun in astrology.

The natural house of Leo is the 5th house, the house of creativity, romantic love, children, play, pleasure and self-expression. This correspondence reinforces the reading of Leo as the sign of creative fulfillment and of the need to show up in the world authentically. To go further: House 5.

Leo's mythological symbolism

The astrological Lion points mainly to the Nemean Lion, an outsized monster that terrorized the region of Nemea in ancient Greece. Its mythological quirk: its hide was invulnerable to every weapon forged by men. No spear, no sword, no arrow could wound it.

Heracles (Hercules) was given the task of killing it as his first labor. Unable to harm it with his weapons, he strangled it with his bare arms. Then, unable to skin the hide with any tool, he used the lion's own claws to cut through it. The Nemean Lion's pelt then became the armor of Heracles, worn as a shield for the rest of his labors.

Several elements of this myth echo in the astrological reading:

• Invulnerability: the Leo archetype is hard to dent in its pride and self-assurance. It takes exceptional force to shake it, or its own weapons turned against it.
• The hide that becomes armor: what made the lion invincible now protects the hero. Leo strength, well integrated, can become a resource for others.
• Solar royalty: the mane, the noble bearing, the natural sovereignty of the king of beasts. The Leo archetype does not seek to rule by force; it radiates an authority that others recognize.
• The courage of the heart: Heracles does not beat the Lion by cunning (Aries), nor by hidden endurance (Scorpio), nor by strategy (Capricorn). He beats it with arms wide open, through direct contact. That is frontal, generous courage, the central quality of the archetype.

Leo's archetypal traits

The characteristics below describe the archetype, not a real person. A full natal chart always modulates these traits through the Moon, the Rising sign, the other planets, the aspects, the houses. Use them as a reading grid, not a verdict.

Archetypal strengths

• Radiance: a natural presence, the ability to "fill the room" with no apparent effort.
• Generosity: emotional warmth, largesse, pleasure in giving and in celebrating the people it loves.
• Natural leadership: inspires trust, brings people together without needing to impose.
• Creativity: artistic expression, a sense of drama, an eye for beauty.
• Loyalty: once its heart is given, it stays. Tradition links it with a deep faithfulness toward loved ones.
• Courage of the heart: faces head-on, with direct bravery, the obstacles that touch what it loves.
• A sense of play: tied to the 5th house, the Leo archetype knows how to celebrate life, to play, to shine in lighter moments.

Friction zones

• Pride: an easily wounded ego is the archetype's direct shadow. Pride, a resource in hard situations, can turn into an obstacle to listening.
• Need for recognition: the Leo archetype needs to be seen, appreciated, applauded. That normal need can become dependence on validation if it stays unintegrated.
• Authoritarianism: the natural pull to take charge can slide into a need for control, or an inability to really delegate.
• Touchiness: a criticism felt as a personal attack, even when it was aimed at an action and not at the person.
• Excess drama: the sign's natural theatricality can amplify conflicts, turning minor disagreements into crises.
• Trouble owning a mistake: the Leo archetype hates losing face. Apologizing takes a conscious effort.
• Putting itself forward: a tendency to take center stage, sometimes without noticing, at the expense of others' space.

These friction zones are not built-in flaws. A worked-on Leo chart can turn touchiness into a sense of its own worth, the need for recognition into creative generosity, pride into dignity. The fixed mode, which can make the archetype resistant to change, is also what gives it the constancy to finish what it starts.

Leo as Sun, Moon, Rising: 3 different readings

This is the point newspaper horoscopes drop every single time: Leo does not mean the same thing depending on which planet sits there in your chart. Here are the three most important readings.

Sun in Leo (~July 23 to August 22)

This is the classic "Sun sign" reading: your conscious identity, what you try to express, what defines you at depth.

Sun in Leo is Sun in domicile. Identity gets built through self-expression, creativity, the capacity to be seen and recognized for who you truly are. The sense of self feeds on the creative act, on direct relationship, on love and attention received.

A Sun-Leo person who cannot express themselves, who lives in invisibility, can feel cut off from something essential. The placement's challenge: learning to shine from the inside rather than depending on an outside gaze to feel real.

Moon in Leo (changes every ~2.5 days)

The Moon describes the emotional world: what feels safe, what nourishes you emotionally, what you need to feel okay.

Moon in Leo carries an emotional need for recognition and love expressed clearly. The emotions run warm, theatrical, generous. The wound comes from indifference or ingratitude far more than from direct confrontation. This Moon feels at ease in moments of celebration, shared love, festivity.

The watch point: a Moon in Leo whose need for warmth goes ignored can develop demanding or dramatic behavior. Recognized and fed, it is one of the warmest and most emotionally generous Moons in the zodiac.

Leo Rising (changes with the time of birth)

The Rising sign is the sign that was rising on the eastern horizon at the moment of birth. It describes the physical presence, the first impression on others, the way you arrive in a room. It is also the cusp of the 1st house.

Leo Rising means a radiant, noble presence that arrives before the words do. A naturally upright bearing, care taken with appearance, an eye for detail in presentation. Others pick up a natural authority and a warmth, sometimes a certain theatricality in the way of moving.

With a Leo Rising, your chart ruler is the Sun, which means the Sun's position in your chart (its sign and its house) becomes decisive for understanding how you present yourself to the world. A Leo Rising with Sun in Virgo will come across very differently from a Leo Rising with Sun in Scorpio.

To understand the mechanics of the Rising sign and the other angles of the chart, see The angles: Ascendant, MC, Descendant, IC.

Leo compatibility: who clicks, who grates?

Astrological compatibility between two people needs a chart-to-chart analysis. Sign-to-sign comparison is a useful caricature to start with, not a sentence. Still, at the level of archetypes, some combinations offer more natural ease or more stimulating friction.

Signs in trine (~120°, flowing)

Trine = same element. Leo (Fire) is in trine with:

• Aries: another Fire sign, sharing enthusiasm, drive, the taste for shining. A fiery duo, sometimes competitive over leadership, but with a very strong common energy.
• Sagittarius: another Fire sign, sharing the sense of celebration, optimism, generosity and the taste for adventure. Sagittarius gives Leo wider horizons; Leo gives Sagittarius a stage to perform on.

Opposite sign (180°, attraction and complementarity)

• Aquarius: Leo's opposite on the individual/collective axis. Leo radiates from its singular self, Aquarius radiates from the idea, the group, the future. Tension between "I shine" and "we shine together". It is one of the most instructive axes in the zodiac: Leo learns detachment from the ego and a feel for the collective; Aquarius learns the warmth of the heart and embodied presence.

Signs in square (~90°, productive tension)

Square = same mode (fixed). Leo is in square with the other fixed signs:

• Taurus: fixed Earth versus fixed Fire. Taurus seeks material security, Leo seeks recognition and creative expression. Both stubborn, they can dig themselves into a stalemate. But their shared loyalty can make this a very solid pairing when it works.
• Scorpio: fixed Water versus fixed Fire. Shared intensity, radically different modes of expression. Leo on the surface (a need for visibility), Scorpio in the depths (a need for secrecy). Classic friction around power, but also mutual fascination.

Signs in sextile (~60°, gentle support)

• Gemini: the mental agility of Gemini sets off Leo's flair for drama, and Leo enjoys the quick wit in return.
• Libra: a shared aesthetic sensibility, a love of beauty and of relationship. Libra tempers Leo's solar tendency to take up all the space; Leo gives Libra the self-assurance it sometimes lacks.

Other relationships

• Leo-Leo: a royal duo, sometimes two suns casting shade on each other. Works well when each has its own space to express itself.
• Leo-Cancer: neighbors. Cancer seeks the emotional security of home, Leo seeks the stage and recognition. Real common ground: loyalty, deep attachment, emotional warmth.
• Leo-Virgo: neighbors. Virgo analyzes and refines, Leo expresses and deploys. Tension around criticism (Virgo criticizes, Leo hates being criticized). In collaboration, they can do great work: vision plus rigor.
• Leo-Pisces: a shared artistic sensibility, but very different emotional needs.

Leo season in transit

Every year, when the Sun enters Leo (around July 23), it is Leo season for everyone, not just for people born under the sign. Symbolically, it is a stretch associated with creative expression, with celebration, with bringing forward what is unique in you.

In the great annual cycle, this is the dead center of summer in the northern hemisphere, heat at its peak, light at its maximum. Tradition reads it as an invitation to play, to create, to express what you carry without holding back too much.

Transits of slow planets (Jupiter, Saturn, Pluto) through Leo mark much longer periods that concern whole generations or entire biographical cycles. For current transits, see the interactive chart.

Tropical vs sidereal: your sign can change

If you use a sidereal system (Indian astrology or jyotish, for example), the dates shift. Someone born on August 5 is:

• Sun in Leo in tropical (about 13° Leo).
• Sun in Cancer in sidereal (with the ~24° shift, called the ayanamsha).

Neither system is "the real one": they are two distinct symbolic systems, built on different astronomical references (seasons versus actual constellations). The technical detail is in Tropical vs sidereal.

Astrolabica lets you switch between the two in its interactive chart so you can see this shift play out on your own chart.
