Virgo runs from August 23 to September 22, the second earth sign of the zodiac and the only one ruled by Mercury rather than a slower-moving planet. The symbol is the Maiden, usually pictured holding a sheaf of wheat, and the sign sits in mutable mode: earth's practicality paired with a mind built for adjustment rather than fixed routine.
People born under Virgo tend to notice what others miss: the typo in the third paragraph, the wobble in a supplier's numbers, the friend who's quieter than usual today. Mercury rulership gives the sign its analytical edge, but Virgo's earth element keeps that analysis pointed at something useful rather than abstract. The result reads as fussy to people who don't share the instinct, and indispensable to people who do.
Green and brown round out the sign's palette in this system, echoing the harvest imagery that shows up across several of Virgo's mythological roots, and Wednesday, Mercury's day, is treated as its ruling weekday.
