21 February is observed as Shaheed Dibosh every year throughout the country in remembrance of the martyrs of Language Movement of 1952. The commemoration begins at the early hours of the day with mourning songs that recall the supreme sacrifices of our language martyrs. People wear black badges and go to the Shaheed Minar in barefoot processions, singing mourning songs. They place wreaths at the Minar. Many of them visit the graves of the martyrs af Azimpur graveyard and pray for them. They also attend various programmes organized in remembrance of the language martyrs.

The UNESCO (United Nations Educational, Scientific and Cultural Organisation) on 17 November in 1999 proclaimed February 21 as the International Mother Language Day in recognition of the sacrifices of the martyrs for the rightful place of Bangla. The day is now annually observed worldwide to promote awareness of linguistic and cultural diversity and multilingualism.
