Deaf Awareness Month:
September is National Deaf Awareness Month, when extra efforts are made to increase awareness of Deaf issues, individuals, and culture. First celebrated in 1958 as the International Day of the Deaf, it soon expanded to the International Week of the Deaf to commemorate the first World Congress of the World Federation of the Deaf, which took place in Rome in September, 1951. Eventually, the week was expanded to include the whole month.
