Thai Pongal is the harvest festival of Tamil Nadu and of Tamil communities across Sri Lanka, Singapore, Malaysia, Mauritius and the wider world. The word pongal means to boil over, and the central act of the day is cooking fresh rice with milk and jaggery in a new pot in the open until it rises and spills over the rim. The family shouts “Pongalo Pongal” at the moment it does, to welcome plenty for the year ahead.
The four days
The festival is a run of four days. Bhogi comes first: old and worn things are cleared out and burned in a small fire, and the house is cleaned and decorated with kolam patterns in rice flour. Thai Pongal is the main day, when the Sun is honoured, the new rice is cooked in the courtyard and offered to Surya along with sugar cane and turmeric plants. Mattu Pongal is the day for cattle, which are washed, decorated with garlands and bells and given sweet pongal, in thanks for their work in the fields. Kaanum Pongal, on the fourth day, is for visiting family and friends and for outings.
The table gives the date of Thai Pongal for each city, with the day before (Bhogi) and the day after (Mattu Pongal) beside it. Kaanum Pongal is the day after Mattu Pongal.
Why the Sun and not the Moon
Pongal is a solar festival, so it has no tithi. It marks the first day of the Tamil month of Thai, which begins when the Sun enters Makara, the sidereal sign Capricorn. This is the same moment as Makar Sankranti, and much of India keeps it under other names: Lohri and Makar Sankranti in the north, Magh Bihu in Assam, Uttarayan in Gujarat. The turn is also thought of as the Sun’s northward journey, the start of Uttarayana. See Makar Sankranti and Lohri.
How the day is chosen
The Tamil calendar counts a day from sunrise and begins a solar month by a sunset rule: if the Sun enters Makara before sunset, that civil day is the first of Thai, and if it enters after sunset, the next day is. This site uses the same rule for Makar Sankranti and Thai Pongal, so the two share a date in every city. Bhogi is the day before and Mattu Pongal the day after.
Why cities differ
The ingress is a single instant. Whether it falls before or after the local sunset depends on where you are. A year when it comes in the late afternoon in India can put it in the early hours of the same morning in New York, and in the evening in Sydney, so Pongal can be a day later in Australia than in India or America in the same year. The table shows each city’s date with that rule applied.
What is cooked
Sweet pongal (sakkarai pongal) is made from new rice, moong dal, milk, jaggery, ghee, cardamom, cashew nuts and raisins. Ven pongal, a savoury version with pepper and cumin, is usually eaten at breakfast on the other days. A traditional lunch served on banana leaves includes vegetables, sambar and payasam. The pot is often tied with a fresh turmeric plant, and a few stalks of sugar cane stand beside it.
A calm note
If you live in a flat or somewhere cold, cooking pongal on a stove and offering it to a lamp is a full and warm observance, and a video call with family covers the fourth day. Communities and temples sometimes follow their own almanac, and if yours names a different day, follow it.
