Leo
The lion: a fixed fire sign ruled by the Sun. The Sun is in Leo from about 23 July to 22 August, the height of summer north of the equator.
Fixed fire, ruled by the Sun
Fixed fire is fire kept burning. The tradition reads Leo as warmth that stays in one place long enough to be felt: generous, proud, loyal and theatrical, needing its light to be seen and willing to give it freely when it is. Aries, the cardinal fire sign, is read as the first flare, and Sagittarius, the mutable one, as fire that travels; Leo is the hearth. Its steadiness makes it dependable and warm-hearted, and the same fixity is read as vanity and a refusal to be told it is wrong.
Leo is ruled by the Sun, the only sign the Sun rules, and it is read as the Sun on its own ground: identity, vitality, the wish to make something and be recognised for it. Saturn, the ruler of the opposite sign, is in detriment here, restraint and duty uncomfortable in a sign of display, and modern astrologers who give Aquarius to Uranus put Uranus in detriment in Leo too. The traditional scheme gives no planet its exaltation or its fall in Leo. Its decans run Saturn, Jupiter and Mars as faces, or the Sun, Jupiter and Mars through the fire signs.
Leo as Sun, Moon and rising sign
The Sun in Leo
The Sun in its own sign is read as a self that shows. A Sun in Leo is described as open-hearted, dramatic in a good cause, generous with praise and attention, and most alive when making or leading something other people enjoy. The tradition attaches a strong sense of dignity to it, and a need to be taken seriously; the same reading lists pride, sulking when overlooked, and a taste for the centre of the room.
The Moon in Leo
A Moon in Leo is read as needing appreciation in order to feel secure: to be noticed, thanked and loved out loud. Its feelings are warm and shown with some flourish, and it is read as loyal and protective towards the people it has taken to heart. Hurt tends to show as wounded pride. The Moon crosses Leo in about two and a half days, so the birth date gives a likely answer and the birth time a sure one.
Leo rising
Leo rising is read as a confident bearing, a certain presence in a doorway and care over appearance, and it makes the Sun the ruler of the chart, so the Sun’s own sign and house carry extra weight. Leo is the natural sign of the fifth house, play, romance and making things. In the northern hemisphere it is among the slowest signs to rise, close to three hours at the latitude of London; at the latitude of Sydney it takes about an hour and a half.
When the Sun is in Leo
The conventional dates are 23 July – 22 August. The Sun arrives at a different hour each year, so the exact moments for this turn of the year are worked out here.
Leo is high summer in the north and the depth of winter in the south. About 7 August, halfway through the sign, the Sun passes the cross-quarter point that older calendars kept as Lammas, the first harvest, also called Lughnasadh. The Sun spends a little over thirty-one days in Leo, still moving slowly just after the Earth has passed its farthest point from the Sun.
The lion
The lion is the Nemean lion, whose hide no weapon could pierce, strangled by Heracles as the first of his labours. The glyph is usually read as the lion’s mane or its tail. The reading keeps the animal rather than its defeat: the king of beasts, courage and a certain magnificence.
Leo and Aquarius across the wheel
Across from Leo is Aquarius, a fixed sign of air. The pair is read as the axis of the individual and the group: Leo the heart that wants to shine as itself, Aquarius the mind that thinks in terms of everyone. It runs through the fifth and eleventh houses, personal creation and shared hopes. Weight across it is read as the question of how to stand out without standing apart, and how to belong without disappearing.
The sign and the constellation
The constellation Leo does look like a lion, a crouching figure whose front is marked by a backwards question mark called the Sickle, with Regulus, the lion’s heart, lying almost exactly on the Sun’s path. The Sun is in front of Leo from about 10 August to 15 September, the end of tropical Leo and most of Virgo. For the first half or so of the sign Leo the Sun is before the faint stars of Cancer. Sidereal Leo begins about 17 August. The page on signs and constellations explains why the three differ.
Common mix-ups
Leo is often described only as vain, which the tradition would call half a reading: pride and generosity come from the same fixed warmth. Births on 22 or 23 July and on 22 or 23 August need a time and a place to say whether the Sun was in Leo, which a birth chart works out. And a Leo Sun does not bring a Leo ascendant with it; the two are independent, and only people born around sunrise have both.
What this page claims
This page sets out how Western astrology reads Leo and where each part of that reading comes from. It describes a vocabulary rather than a person, and it predicts nothing about anybody born with the Sun, the Moon or the ascendant in Leo.
Questions people ask
When is Leo season?
Leo season runs from about 23 July to 22 August. In recent years the Sun has entered Leo on 22 or 23 July and left for Virgo on 22 or 23 August, depending on the year and the time zone. North of the equator it is high summer and south of it midwinter, but the dates are the same in both hemispheres.
What is Leo’s ruling planet?
Leo is ruled by the Sun, the only sign the Sun rules, and it has no modern co-ruler. Strictly the Sun is a star, but astrology counts it among the planets in the old sense of a body that wanders against the fixed stars. Saturn is in detriment in Leo, and the traditional scheme places no exaltation or fall there.
What does a Leo Moon mean?
A Leo Moon is read as an emotional nature that needs warmth, recognition and loyalty, and gives the same in return. The tradition describes it as big-hearted and expressive, and as hurt more by being overlooked than by being criticised. The Moon sign comes from the Moon’s position at birth, which changes every two or three days, so it is often different from the Sun sign.
Which signs are said to suit Leo?
The tradition gives no verdict on pairs, but it does compare elements. Leo shares fire with Aries and Sagittarius, a trine read as instinctive understanding, and sits sixty degrees from the air signs Gemini and Libra, read as lively exchange. Taurus and Scorpio square it, read as fixed signs that do not easily give way. Comparing two whole charts shows far more than two Sun signs.
