Leo — the Fire sign of the lion-hearted

July 23 – August 22 · ruled by The Sun · known in Vedic astrology as Simha

The heart of the zodiac

Leo is the only sign ruled by the Sun — and it shows. Where other signs borrow light, Leo generates it. Born under the Fixed Fire of high summer, Leos carry a natural warmth that draws people in and a steadiness that keeps them there. The lion isn't loud for attention's sake; it's loud because a full heart is hard to keep quiet.

The Fixed quality gives Leo its underrated superpower: loyalty. Aries starts the fire and Sagittarius spreads it, but Leo tends it — to friendships, creative projects, and causes, often for decades. The shadow side is pride: a Leo would rather burn quietly than admit the flame needs tending by someone else.

Love & relationships

Leo loves the way it does everything else — wholeheartedly and a little theatrically. Grand gestures come naturally, but what a Leo actually needs is simpler: to feel seen. Praise a Leo's effort, not just their results, and they will move mountains for you. Ignore them, and the sulk is legendary. Fire signs (Aries, Sagittarius) match Leo's pace; Air signs (Gemini, Libra, Aquarius) fan the flame with ideas and admiration.

Career & money

Leos thrive where there's a stage — which doesn't have to mean a literal one. Leadership, teaching, design, performance, brand-building: anywhere visibility and creative ownership meet. Money flows in generously and out just as generously; the Leo lesson is that saving is also a form of self-respect.

In Vedic astrology: Simha

In the Vedic tradition Leo is Simha, likewise ruled by Surya, the Sun. Because Vedic astrology uses the sidereal zodiac, your Vedic Sun sign may differ from your Western one — many Western Leos discover a Cancer (Karka) Sun in their Kundli. Simha contains the nakshatras Magha, Purva Phalguni and part of Uttara Phalguni, each coloring the royal sign differently: ancestral authority, artistic pleasure, and generous duty.

Frequently asked

What are Leo's dates?

The Sun is in Leo from about July 23 to August 22 in the Western (tropical) zodiac. In Vedic (sidereal) astrology the Sun occupies Simha roughly August 17 to September 16, so your Vedic Sun sign can differ.

Who is Leo most compatible with?

Leo pairs naturally with fellow Fire signs Aries and Sagittarius, and finds an admiring, idea-rich match in Air signs Gemini, Libra and Aquarius. The famous challenge pairings are Taurus and Scorpio — fixed signs that won't yield the throne either.

What planet rules Leo?

The Sun rules Leo — the only sign it rules. In Vedic astrology the same is true: Simha is ruled by Surya. That's why identity, visibility and creative self-expression are core Leo themes.

What is Leo's lucky color?

Gold and warm sunset shades amplify Leo's natural radiance. Traditional astrology suggests Leos avoid heavy maroon tones on important days.
