World Autism Awareness Day or World Autism Acceptance Day is an internationally recognized day (observed annually on 2 April) that encourages member states of the United Nations to take measures to raise global awareness of autism, promote the acceptance, appreciation and inclusion of autistic individuals and recognize such individuals' local and global contributions. The date was chosen to mark the beginning of World Autism Awareness Month, an observance which serves a similar purpose.
