When is Kokborok Day or Tripuri Language Day celebrated?

A state-observed 'Day' commemorating a language or cultural cause in India is tied to the actual historic milestone behind that cause — an official government notification, enactment, or decisive movement event — not to an arbitrary calendar date.

In Tripura, Kokborok was formally notified as an official language of the state on 19 January 1979. Every year, this date is observed as Kokborok Day, also called Tripuri Language Day, to mark that recognition.

• 10th January: no official notification or annual observance tied to Kokborok's recognition is recorded on this date.

• 15th January: no Kokborok-related notification or state observance is linked to this date.

• 20th January: this date does not correspond to any official record of Kokborok's language recognition in Tripura.

Government of Tripura and TTAADC publications on Kokborok record 19 January as the observance date, corroborated by independent media coverage of the annual Kokborok Day commemoration.
