Born on July 22, 23, or 24?

Because the Sun shifts from Cancer to Leo at fluctuating UTC hours, standard date tables are prone to error. Verify your exact degree with our astronomical calculators.

What Is the Leo Sun Sign Placement?

In Western tropical astrology, your Leo Sun sign indicates that at your exact moment of birth, the Sun occupied the sector between 120°00'00" and 149°59'59" of ecliptic celestial longitude. As the fifth station of the zodiac, Leo marks the high summer season—a phase where life expresses its fullest vitality, creative pride, and individual magnificence.

Leo is unique because the Sun is in its domicile (home rulership). While your social presentation is guided by your Rising Sign Calculator and your subconscious instincts are processed in the Moon Sign Calculator, the Leo Sun is the beating heart of your birth chart, generating authentic self-expression and generous warmth.

Who Is the Leo Personality Archetype?

Ruled by the Sun, the Leo archetype is The Monarch, The Creator, or The Performer. Leos are driven by an instinct to bring joy, radiance, and bold structural vision to their communities, naturally attracting followers through charismatic authenticity.

Solar Strengths

  • Radiant generosity: naturally mentors, encourages, and elevates others.
  • Creative conviction: fearless dedication to artistic vision and authentic expression.
  • Unshakable loyalty: defends allies with lion-hearted bravery and open integrity.
  • Executive presence: naturally assumes responsibility and inspires teams through crises.

Shadow Trait Vulnerabilities

  • Validation vulnerability: deep sensitivity to feeling ignored or unappreciated.
  • Autocratic pride: difficulty admitting errors or taking subordinate advice.
  • Theatrical overstatement: dramatizing minor disagreements into heroic sagas.
  • Stubborn fixedness: resisting operational changes that originate outside themselves.

When Does Leo Begin? The 2020–2026 Solar Ingress Drift

Because Earth's orbit is approximately 365.2422 days, the Sun's entry into 0°00'00" Leo shifts across a wide 24-hour window depending on the leap-year cycle. In 2023, for example, the Sun did not enter Leo until July 23 at 01:50 UTC, meaning all births on July 22, 2023 were astronomical Cancer Suns.

Leo Sun Sign Frequently Asked Questions

What are the exact calendar dates for the Leo Sun sign?

Leo typically spans from July 22 or 23 through August 22 or 23. Because the tropical solar year is roughly 365.2422 days, the Sun's exact ingress into 0°00' Leo shifts by several hours every year. In some years, Leo begins on July 22, while in others (such as 2023), it does not begin until the early hours of July 23 UTC.

How do I know if my July 22–23 birthday is Cancer or Leo?

The Sun changes signs at an exact UTC minute each year. In 2022, the Sun entered Leo on July 22 at 20:07 UTC, while in 2023 it entered on July 23 at 01:50 UTC. If your birth occurred before the exact ingress minute for your birth year, your Sun sits at late 29° Cancer; if born after, you are a 0° Leo Sun.

What does Fixed Fire mean in Leo psychology?

Fire represents enthusiasm, passion, and spirit, while the Fixed modality represents stabilization, endurance, and concentration of purpose. Unlike the explosive, pioneering spark of Cardinal Fire (Aries) or the dispersing embers of Mutable Fire (Sagittarius), Fixed Fire is the hearth: sustained, radiant heat that maintains creative confidence over decades.

How does the Sun rule the Leo Sun sign?

Leo is the only zodiac sign ruled by the Sun itself—the center of our solar system. In astrology, this planetary dignity (domicile) grants Leo individuals an innate drive toward self-realization, personal sovereignty, authentic creative self-expression, and natural stage presence.

What is the biggest shadow vulnerability for Leo?

Because Leo's identity is anchored in solar validation, its primary shadow vulnerabilities are excessive pride, taking indifference personally, and struggling to share the creative spotlight. When mature, Leo's light is generous, elevating others rather than demanding adulation.
