Festival Calendar 2025

Key Festivals Explained

Pongal (14–17 January)

The biggest and most beloved Tamil festival, Pongal is a four-day harvest celebration thanking the Sun God and farm animals for a successful harvest. Day 1 (Bhogi) involves discarding old items and cleaning homes. Day 2 (Thai Pongal) is the main celebration where fresh rice is cooked until it overflows the pot — symbolising abundance. Day 3 (Mattu Pongal) honours cattle, and Day 4 (Kaanum Pongal) is for family outings.

Tamil New Year — Chithirai Puthaandu (14 April)

The Tamil calendar year begins on the first day of the month Chithirai. Families clean and decorate their homes, visit temples, and read the Panchangam (almanac) for the year ahead. A special meal called "Maanga Pachadi" is prepared — it combines six flavours (sweet, sour, salty, bitter, pungent, astringent) representing the different experiences life will bring in the new year.

Aadi Perukku (2 August)

Celebrated on the 18th day of the Tamil month Aadi, this festival honours water bodies — rivers, lakes, and the sea. It is particularly significant along the banks of the Kaveri and other Tamil Nadu rivers. Families prepare a feast and offer prayers near water, thanking nature for irrigation that sustains agriculture.

Navaratri (22 September – 2 October)

Nine nights dedicated to Goddess Durga, Lakshmi, and Saraswathi. In Tamil Nadu, the Kolu (Golu) tradition is central — families set up a stepped display of dolls and figurines, visit each other's homes, exchange sundal (chickpea snacks), and sing devotional songs. Saraswathi Puja on the ninth day is important for students and professionals.

Karthigai Deepam (5 December)

The festival of lights unique to Tamil Nadu (different from Deepavali). Homes are illuminated with oil lamps, and the Mahadeepam is lit atop Tiruvannamalai hill — visible for kilometres. The lighting represents the triumph of knowledge over ignorance.
