World Autism Awareness Day is an internationally recognized day on April 2 every year, encouraging Member States of the United Nations to take measures to raise awareness about people with Autism Spectrum Disorder throughout the world. It was designated by the United Nations General Assembly resolution (A/RES/62/139). World Autism Awareness Day”, passed in council on 1 November 2007, and adopted on 18 December 2007. It was proposed by Mozah Bint Nasser Al-Missned, the United Nations Representative from Qatar and consort to Emir Hamad Bin Khalifa Al-Thani, and supported by all member states.
This resolution was passed and adopted without a vote in the UN General Assembly, mainly as a supplement to previous UN initiatives to improve human rights.
World Autism Day is one of only seven official health-specific UN Days. The day itself brings individual autism organizations together all around the world to aid in things like research, diagnoses, treatment, and acceptance for those with a developmental path affected by autism.
The terms “Autism Awareness Day” and “Autism Awareness Month” are often contested by autism rights advocates, who claim that they feed into perceived ableism against autistic people. Such groups, including the Autistic Self Advocacy Network, advocate using the term “Autism Acceptance day” as an alternative for both events under the belief that it promotes overcoming anti-autism prejudice rather than simply increasing awareness of autism.
