National ASL Day
Wednesday, April 15, 2026
Today is National ASL Day. National ASL Day celebrates both the existence and history of American Sign Language. On 15 April, 1817, the institution later renamed the American School for the Deaf opened. Village sign languages, like Martha’s Vineyard Sign Language, intermingled there with French Sign Language forging modern ASL.
