Sankranti is considered to be an auspicious day because the festival 'Makar Sankranti' is celebrated in various regions of India. ‘Makar Sankranti’ is the harvest festival, whereby it marks the onset of the harvest season in India and thus is celebrated all across the country. It has various local names and is known as Pongal in the states of Andhra Pradesh and Tamil Nadu, Maghi and Lohri in Punjab and in Assam it is known as Bihu.
Going by the Bengali calendar ‘Makar Sankranti’ is usually celebrated on the very last day of the Bengali month of winter 'Poush' thus giving rise to the name 'Poush Sankranti’. To commemorate this very special day in any Bengali’s calendar the families usually prepare an array of home-made sweetmeats like Puli Pithe, Patishapta Pithe, Doodh (Milk) Puli and many other indigenous varieties of puli and pithe. These sweets are special owing to the fact that they are made using rice flour with inner fillings consisting of grated coconut.
