Explanation:

Birsa Munda was born on 15 November 1875, at Ulihatu in Bengal Presidency, now in the Khunti district of Jharkhand, on a Thursday, and hence named after that day, according to the then prevalent Munda custom. The folk songs reflect popular confusion and refer to both Ulihatu and Chalkad as his birthplace. Ulihatu was the birthplace of Sugana Munda, father of Birsa. The claim of Ulihatu rests on Birsa's elder brother Komta Munda living in the village, where his house still exists albeit in a dilapidated condition.
