About World Autism Awareness Day
World Autism Awareness Day is observed on 2 April. It was designated by the UN General Assembly in 2007 to raise awareness of autism and to promote the rights, inclusion and full participation of autistic people in society.
The UN General Assembly designated 2 April as World Autism Awareness Day in 2007, and it has been observed since 2008. The day highlights the need to improve the lives of autistic children and adults so they can take part fully in society.
Autism is a lifelong neurological difference that affects how a person communicates, experiences the senses and relates to others. It shows up very differently from one person to the next. Many autistic people and advocates now speak of acceptance rather than only awareness, meaning respect for autistic ways of being and support that fits each person.
How it is marked
Schools, therapy centres, parent groups and workplaces hold talks, sensory-friendly events and sessions led by autistic speakers. Some buildings are lit in blue, while many in the autistic community prefer symbols such as the rainbow or gold infinity sign. In India, parent support groups and special educators often use the day to share information about early support and inclusive schooling.
What to write
