Communication Shutdown is a global fundraiser on behalf of autism-related organizations in more than 40 countries.[1] Beginning in 2010, the day is commemorated by individuals voluntarily refraining from using social media such as Facebook or Twitter for one day on 1 November.[2]
The concept of the event is based on the idea that social communication is difficult for autistic people. Going without social networks for one day is therefore a perspective-taking exercise for people not on the spectrum.[3]
