Libra () is the seventh astrological sign in the Zodiac. It spans the 180–210th degree of the zodiac, between 180 and 207.25 degree of celestial longitude. Under the tropical zodiac, Sun transits this area on average between (northern autumnal equinox) September 22 and October 21, and under the sidereal zodiac, the sun currently transits the constellation of Libra from approximately October 16 to November 17. [1][2] The symbol of the scales is based on the Scales of Justice held by Themis, the Greek personification of divine law and custom.[3] She became the inspiration for modern depictions of Lady Justice. The ruling planet of Libra is Venus.[4][5] Libra is one of the three zodiac air signs, the others being Gemini and Aquarius. Libra sign is symbolized by the gryphon, a mythological creature with the head, wings and talons of an eagle and hind legs of a lion.

According to the Tropical system of astrology, the Sun enters the sign of Libra when it reaches the southern vernal equinox, which occurs around September 22.
