Today is World Autism Awareness Day. There are many ways you can create awareness, but today we're asking you to Light It Up Blue. Here's how you can do that.

Each April 2, Autism Speaks celebrates Light It Up Blue along with the international autism community, in commemoration of the United Nations-sanctioned World Autism Awareness Day. Light It Up Blue is a unique global initiative that kicks-off Autism Awareness Month and helps raise awareness about autism. In honor of this historic day, many iconic landmarks, hotels, sporting venues, concert halls, museums, bridges and retail stores are among the hundreds of thousands of homes and communities that take part to Light It Up Blue.
