Lachit Day, also known as Lachit Divas, is observed in the Indian state of Assam every November 24 to commemorate the birthday of Lachit Borphukan, a renowned military commander of the Ahom Kingdom. Born on November 24, 1622, Lachit is celebrated for his pivotal role in protecting Assam from the Mughal Empire, particularly during the Battle of Saraighat in 1671, where he successfully defended Guwahati against a large Mughal force. The day is marked by wreath-laying ceremonies at statues of Lachit throughout Assam, honoring his heroism and loyalty to his kingdom. This observance reflects the significance of Lachit's contributions to Assamese history and culture, reinforcing his status as a national hero in the region.
