Today marks the eighth annual World Autism Awareness Day. Every year, autism organizations around the world celebrate the day with unique fundraising and awareness-raising events, and of course by going blue!

Monuments around the world ranging from the Sydney Opera House to the Empire State Building to the Leaning Tower of Pisa—all over Europe, Asia, the Middle East, Canada, Mexico, Latin America, even The Holy Redeemer in Rio will be lit up blue today to honor the millions impacted by autism.

Do your part in your community or on social media using the hashtag #LIUB to help send love to the millions impacted by Autism around the world.
