Leo is the fifth astrological sign of the Zodiac, originating from the constellation of Leo. It's found in the eastern sky. In western astrology, this sign is no longer aligned with the constellation as a result of the precession of the equinoxes. In astrology, Leo is considered to be a "masculine", positive (extrovert) sign. It is also considered a fire sign and is one of four fixed signs. Leo is ruled by the Sun.

Individuals born when the Sun was in this sign are considered Leo individuals. Under the tropical zodiac, the Sun is in Leo roughly from July 23 to August 22. Under the sidereal zodiac, it is currently there roughly from August 17 to September 16.
