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 23 and October 22, and under the sidereal zodiac, the sun currently transits the constellation of Libra from approximately October 16 to November 15.[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.
