The International Day of Sign Languages is observed on 23 September, every year.

• This day provides an opportunity to support and save the linguistic identity and cultural diversity of deaf people. Sign language helps to create unity among people; therefore, it is important to observe the day.
• Sign languages are structurally different from spoken languages. As per sources, there are approximately 72 million deaf people in the whole world. We should all recognise the national sign languages that are a part of our country's linguistic landscapes.
• The theme of this year Sign Language Day-2023 is “A World Where Deaf People Everywhere Can Sign Anywhere!”A world where deaf people are seen as a part of the natural range of human diversity, and national sign languages are celebrated and used everywhere as part of national societies.
