Bhogi (భోగి: Telugu) (போகி: Tamil) is the first day of the four-day Pongal festival. According to the Gregorian calendar it is normally celebrated on 13 January but sometimes it is celebrated on 14 January. In Tamil Calendar, this corresponds to last day of the Tamil month Maargazhi. It is a festival celebrated widely in Tamil Nadu, Andhra Pradesh and Telangana.
On Bhogi, people discard old and derelict things and concentrate on new things causing change or transformation. At dawn, people light a bonfire with logs of wood, other solid-fuels and wooden furniture at home that are no longer useful. The disposal of derelict things is where all old habits, vices, attachment to relations and material things are sacrificed in the sacrificial fire of the knowledge of Rudra, known as the "Rudra Gita Jnana Yajna". It represents realisation, transformation and purification of the soul by imbibing and inculcating various divine virtues. Bhogi is celebrated the day preceding Thai Pongal, Makar Sankranti and Lohri.
Bhogi is an upcoming Tamil and Telugu bilingual film directed by Pandian, starring Trisha, Poonam Bajwa and Oviya in the leading roles. The film, which is simultaneously being made in Telugu with the title Memu, began production in 2013.
