If you’ve seen a blue puzzle piece logo on Facebook or a post about the Empire State Building going blue, you’ve probably heard the slogan, “Light it Up Blue.” This isn’t just a friendly decoration to ring in spring. Light it Up Blue is the call to action for organizations and individuals around the world to get involved in World Autism Awareness Day on April 2nd. Autism is a developmental disorder which interferes with social, behavioral and communication skills. World Autism Awareness Day began six years ago when the United Nations General Assembly unanimously chose that date as an annual day to “highlight the need to help improve the lives of children and adults who suffer from the disorder so they can lead fill and meaningful lives.”
