Sūrya Narāyaṇa — at Pongal

Sūrya at Pōṅgāl — the Sun and the southern harvest

The first day of the harvest, given to the Sun

Pōṅgāl is the Tamil harvest festival of the month of Tai (January), the four days of which are Bhōgi, Tiruvuvāṟu, Mattu Pōṅgāl and Kāṇum Pōṅgāl. It is a solar festival — a thanksgiving to Sūrya, the Sun — and it is the one festival in which the Sun is worshipped in almost every Tamil household rather than at a temple. On the morning of the day, rice is boiled with milk and ghee in a copper or earthen pot until it overflows — the overflow, pōṅgāl, gives the festival its name — and the pot is offered to the Sun in the east-facing part of the house, often on a stone or a decorated stand, with til (sesame), the sugarcane, and the first fruits. In a real sense the festival is about the household's own hearth, and the Sūrya shrine at the courtyard is domestic.

Bhōgi, the first day, is the festival of enjoyment and of the cattle. It is the day of the communal feast — bhōg, the share of the year's first fruits, eaten together — and it is also the day on which the working animals are decorated with māṅgai (turmeric) and ash, garlanded, and thanked; Mattu Pōṅgāl is the day of the cattle, and in many villages it is the day of the bull-race (jallikattu — the Tamil bull-taming custom). The Sūrya Pūjā proper is performed with the til and the sugarcane, the gopuram of the house facing east, and the household rite being distinct from the temple pūjā even though many families also go to a Nāravaṇa / Navagraha shrine that morning.

The Sūrya dimension of the festival is regional and has widened. Pōṅgāl is now celebrated by Tamil communities in Sri Lanka, Malaysia and Singapore, and in much of the diaspora it has partly become a Tamil New Year rather than a solar offering, with the Sūrya element surviving in a til-and-sugarcane household rite. The corpus frontmatter's "household" emphasis is correct and is the important part: this is a festival in which the deity is genuinely present in the house, not only at the shrine. Its dates shift with the Tamil solar calendar, so any printed Gregorian date is secondary.

Sources and what is still unverified

• The Tamil ōl (oral) literature and the household kūṭam ritual manuals; a specific Tamil study of the Sūrya pūjā at Pōṅgāl is required and is not on file here.
• Kinsley, Hindu Goddesses — for the solar-goddess in South Indian practice.
• District Gazetteers of the Tamil Nadu districts (Government of India gazetteer series) — for the village festival as recorded by the administration.
• Unverified: the "Bhogi" etymology, the frontmatter's "Tamil" label as a tradition rather than a ritual text, and every festival date given in the frontmatter.
