“Makaradi — Makaradi snana, Magh Bihu (Assam), Tila samkranti, Pongal (S. India), Bhogi (S. India — on the day before Pongal), Mattu Pongal (S. India — on the day after Pongal).” Calendar Reform Committee 1955, General Rules for Religious Festivals, p. 106. “The Tamil rule: In the Tamil districts the rule is that when a samkranti takes place before sunset, the month begins on the same day, while if it takes place after sunset the month begins on the following day.” Calendar Reform Committee 1955, Rules of Samkranti, p. 244. The rule that heads the solar festivals, the day "taken to begin from midnight" (p. 106), is not applied to Pongal. It is kept on the first day of the month of Makara as the Tamil districts count it, a transit after sunset going to the next day (p. 244); the Rashtriya Panchang prints Pongal so.
