Explanation:

The festival is now a new innovation of the Tai-Ahom as believed by many quarters. In fact, its antiquity dates back to some two thousand years back when Lengdon (the Lord of Heaven) who happened to be the first progenitor of the Tai-Ahom, sent down two of his grandsons Khun-Lung and Khun-Lai to earth to found a state. He advised them to celebrate this festival annually by making offerings and oblations to Him to continue their uninterrupted political hold over the masses. During the days of the Ahom Kings, Me-Dam-Me-Phi celebration was attended by the kings and his ministers and other higher officials as well as a great number of people. It was celebrated at Charaideo, the religious centre of the Ahom kings, with the huge burial mounds (maidams) standing there as a witness. The celebrations at that time lasted for several days. The observance of Me-dam Me-phi continued.  At present the Ahom people observe Me-Dam Me-Phi communally all over Assam on 31st of January each year, and are attended by other people as well. Recognizing the importance of the day, the Government of Assam declares this day as public holiday.
