Held annually on February 21, this is the 18th IMLD observance. IMLD is coordinated on the international level by UNESCO, but countries, communities, and associations organize local observances around the world. There have also been initiatives online, such as the Rising Voices "Mother Language Meme Challenge."
In a letter marking IMLD 2017, the African Academy of Languages is requesting information about local observances and initiatives in Africa after they are held.
The Linguapax Institute announces the winner of the Linguapax Prize annually on IMLD. This year's award went to Dr. Matthias Brenzinger, who is described on the Linguapax site as:
