About the Leo zodiac sign
Leo — the Lion — is the fixed fire sign of the zodiac, ruled by the Sun. Leo energy is warm, generous, and built for spotlight without apology. Famous Leo celebrities include Barack Obama, Madonna, Jennifer Lopez, Mick Jagger, and Daniel Radcliffe. The Leo signature is presence — Leos enter a room and the room reorients without anyone announcing it.
How Leo sun signs are determined
A Leo Sun sign means someone was born when the Sun was in Leo (July 23 - August 22). Because the Sun rules Leo, the Sun sign is unusually defining for this group — Leo charts almost always foreground their Sun house and aspects.
