02 April – World Autism Awareness Day-Stamps on Autism
World Autism Awareness Day was established on December 18, 2007 by the United Nations. The General Assembly put together resolution 62/139, which consisted of four major elements. The day was meant to include the participation of all UN organizations and its member states. World Autism Awareness day was created as a dedication to raising awareness of autism in the general community. 02 April is observed as World Autism Awareness Day every year.
Autism affects approximately 1 out of every 150 children around the world. It is a neural development disorder that affects their ability to socialize normally by impacting their abilities to utilize verbal and non-verbal communication. Since 2012, there has been a 30% increase in the amount of children being affected with autism, and World Autism Awareness Day helps to bring awareness to this growing health concern. Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects communication, behavior, and social interaction. It exists on a spectrum, meaning individuals experience it differently.
In recent years, the focus has shifted from awareness to acceptance, dignity, and inclusion, reflecting a broader understanding of neurodiversity
The theme for 2026 is: “Autism and Humanity – Every Life Has Value.”
