Leo runs July 23 – August 22. Today's Leo horoscope covers love, money, and energy, and is updated every morning.
Your sun sign is the zodiac sign the Sun was passing through on the day you were born. For Leo that is roughly July 23 to August 22, though the exact cutoff shifts by up to a day from year to year, so anyone born on the edge should check their birth time against a calculated chart rather than a calendar. Being a Leo does not mean the Sun was in the constellation Leo as an astronomer would describe it; Western astrology uses the tropical zodiac, which is anchored to the seasons rather than to the visible star field.
Leo is the only sign ruled by the Sun itself. Every other sign answers to a planet that moves, changes speed, and turns retrograde. The Sun never does. That single fact explains most of what astrologers say about Leo: constancy, warmth, a fixed centre, and a refusal to be ambiguous about who they are.
Warm. The most consistent Leo signature is heat directed outward. Leos tend to be the person who notices the quiet one at the table. Generosity here is not a performance of virtue, it is closer to a reflex.
Proud. Leo pride is often described as vanity. It is more accurately a low tolerance for being made small. A Leo will take a hard critique of their work far better than a casual dismissal of it.
Loyal. Fixed signs commit and then stay. Leo's loyalty is personal rather than institutional: they are faithful to people, not to systems.
Dramatic. Leos externalise. Feelings arrive at full volume and get expressed rather than processed privately. This reads as theatre to earth and air signs, and as honesty to fellow fire signs.
Stubborn. The fixed modality means Leo digs in. Changing a Leo's mind works through appreciation, not pressure. Corner them and the position hardens.
Sensitive to being ignored. The real Leo wound is not criticism. It is indifference.
The three fire signs share a temperament — motivated, expressive, forward-leaning — but the modality splits them:
Aries (cardinal fire) starts things. Ignition. Leo (fixed fire) sustains things. A hearth rather than a match. Sagittarius (mutable fire) spreads things. Sparks carried on wind.
Fixed fire is the reason a Leo can carry a project, a friendship, or a room for years. It is also the reason a Leo who has decided something is over is genuinely difficult to move.
Each sign has a natural house. Leo's is the fifth: creativity, romance, play, performance, and children. This is the part of a chart that asks what you make for the pleasure of making it. It is not the house of career or duty. Astrologers reading a Leo emphasis look for where someone gets to be delighted rather than merely competent, and Leos tend to go flat, fast, in lives with no room for that.
Sun-sign compatibility is the shallowest layer of a real compatibility reading. A full synastry comparison weighs Moon, Venus, Mars, and the angles between two whole charts. With that caveat:
The lion of the constellation is the Nemean lion of Greek myth, whose hide no weapon could pierce. Heracles could not cut it, so he strangled it and afterwards wore the skin as armour. The image is worth sitting with, because it is not a story about ferocity. It is a story about a creature whose defining quality is that it cannot be wounded from the outside, and whose skin, once given, protects someone else.
Older layers run beneath the Greek version. In Egyptian and Mesopotamian sky-lore the lion was tied to the height of summer, the Sun at full strength, and the Nile's annual flood. Leo has been associated with royalty for as long as there are records of it being associated with anything.
"Leos are attention-seeking." Leo wants to be recognised, which is not the same as wanting to be watched. Plenty of Leos are quiet people who simply need their contribution named.
"Leos are arrogant." Confidence in Leo is usually louder than the underlying certainty. The sign that most visibly performs self-assurance is often the one checking hardest whether it landed.
"Your sun sign is your personality." It is one factor. Your Moon (inner life), rising sign (how you meet the world), and Venus and Mars (how you love and act) can pull a chart a long way from the sun-sign stereotype.

Born July 22–24 or August 21–23? The Sun's sign change happens at a specific moment, not at midnight, and it moves year to year. There is no such thing as being half Leo, half Virgo. You are one or the other, and a calculated chart settles it in seconds.
