The International Day of Sign Languages is commemorated on this day since the World Federation of the Deaf (WFD) was founded on this day in 1951, as a result of efforts by the WFD in 2017.
Did you know there are around 72 million deaf individuals in the world? The World Federation of the Deaf provided this data. Over 300 distinct sign languages are used by these people together. Many people are unaware that sign languages are natural languages in their own right.
