- 18th day of Aadi
- Early August
- Kaveri delta, Tamil Nadu
Where it began
Perukku means rising. In Aadi, the monsoon fills the rivers, and the Kaveri rises to feed the fields. The day thanks the river, seen as a goddess, for her blessing.
The festival is also called Padinettam Perukku, the eighteenth-day rising. The number 18 is linked with the Kurukshetra war and the eighteen chapters of the Bhagavad Gita, as some stories tell.
How it grew over time
Sangam age
Poems praise the Kaveri and describe river festivals in the Chola country.
Chola times
Dams like the Grand Anicut, built by Karikala Chola, made the Kaveri the lifeline of the delta.
Medieval period
Temple festivals along the Kaveri at Srirangam and Thiruvaiyaru marked the rising of the river.
