International Stuttering Awareness Day (ISAD), or International Stammering Awareness Day, is an annual celebration held on October 22. It was first held in the UK and Ireland, in 1998. The day is intended to raise public awareness of the issues faced by millions of people – one percent of the world's population– who stutter, or stammer.
Every year, stuttering communities and associations around the world get together, put on events and campaign to highlight how certain aspects of society can be difficult for people who stammer.
