Bhogi Pandigai / Bhogi Pallu / Lohri / போகிப்பண்டிகை / போகிப் பள்ளு / லோஹ்ரி
The day preceding Pongal is called Bhogi when people discard old things and focus on new belongings (பழையன கழிதலும் புதியன புகுதலும்). The disposal of derelict things is similar to Holika in North India. The people assemble at dawn in Tamil Nadu and Andhra Pradesh to light a bonfire to discard old used possessions. The house is cleaned, painted and decorated to give a festive look. In villages, the horns of oxen and buffaloes are painted in colors and in most rural parts of Andhra Pradesh people celebrate it in a grand way as most of them would have their harvest ready or even would have made money out of the harvests.
This tradition is observed on the same day in Andhra Pradesh where it is also called "Bhogi." The fruits from the harvest are collected (such as regi pallu and sugar cane), along with flowers of the season, in a ceremony called Bhogi Pallu Money is often placed into a mixture of Bhogi Pallu, and the mixture is poured over children, who then collect the money and sweet fruits.
This day is celebrated in Punjab as Lohri and in Assam as Magh Bihu / Bhogali Bihu.
