International Day of Sign Languages

International Day of Sign Languages History

International Day of Sign Languages (IDSL) aims at raising awareness about the critical role sign languages play in the lives of deaf and hard-of-hearing people. With over 200 different sign languages around the world, this observance promotes the significance of these languages in ensuring full and effective communication access, as well as protecting the cultural and linguistic rights of deaf people. It serves as an opportunity for society to recognize and support linguistic diversity, enabling deaf individuals to access education, healthcare, and other vital services and participate more inclusively in their communities.

The United Nations General Assembly first proclaimed IDSL in 2017. For Americans, this observance is particularly relevant as it not only supports the preservation of American Sign Language (ASL) but also fosters deeper understanding of Deaf culture and experiences in the United States. ASL is recognized as the primary sign language used by approximately 500,000-2,000,000 deaf people in America and is the third most commonly used language in the country.

In the United States, International Day of Sign Languages is celebrated with various activities and events, including ASL workshops, Deaf cultural presentations, and performances by deaf artists. These initiatives provide valuable platforms to learn about and engage with the Deaf community, as well as to celebrate the cultural and linguistic diversity of American Sign Language. International Day of Sign Languages is observed on September 23 each year.
