April 2 is World Autism Awareness Day — and April is World Autism Month — during which thousands of buildings, landmarks and homes around the world will “light it up blue.” And now, thanks to the efforts of Truro resident Amy Rogers, whose daughter, Anna, 17, has autism, the Pilgrim Monument in Provincetown will be bathed in blue light starting Tuesday night, and continue to be lit blue nightly for the rest of the month.

Crown & Anchor DJ Chris Racine will help cover the floodlights of the monument with blue gels.

World Autism Awareness Day was created by a resolution of the United Nations General Assembly in 2007 to educate people worldwide about autism spectrum disorder.
