About National American Sign Language Day

National American Sign Language Day is observed on April 15 in the United States to celebrate ASL, Deaf communities and access to language.

The date recalls the opening of the American School for the Deaf on April 15, 1817; state institutions recognize the modern awareness day, but this is not the same as a federally mandated paid holiday.

Why National American Sign Language Day matters

American Sign Language is a full natural language with its own grammar and cultural traditions. It is not simply an English word-for-word hand code.

Celebrating the day can encourage access to sign-language learning, qualified interpretation and Deaf-led arts and education.

History of National American Sign Language Day

The American School for the Deaf documents that its school opened on April 15, 1817 in Connecticut with Thomas Hopkins Gallaudet and Laurent Clerc central to the founding.

California’s Commission on Disability Access identifies April 15 as the annual date for National ASL Day and connects it to the school anniversary.

The school’s founders founded that institution, not necessarily the modern ASL Day campaign; the reviewed material is insufficient to name a single original observance creator.
