THE QUIRKY, REBEL-WITH-A-CAUSE, HUMANITARIAN SIGN OF THE ZODIAC. This bunch are uniquely awesome. If you're born between January 20 and February 18, you're an Aquarius - which means you're born to break the mold, think outside the box, and maybe invent something weird and brilliant. Aquarians are an air sign ruled by Uranus (the planet of revolution), so expect them to be quirky like they're from a futuristic movie, humanitarian like they're running a charity marathon, and detached like they're observing from a space station. Aquarians = innovation + weirdness + good vibes.
