Answer for your own region, but notice first that almost every Indian harvest festival falls in one of two windows — mid-January, when the winter crop is cut in the south and the sun turns north, and spring or autumn, when the region's own main crop ripens.
| Festival | Region | When | How it is celebrated |
|---|---|---|---|
| Pongal | Tamil Nadu | mid-January (four days) | New rice, jaggery and milk are boiled in a clay pot until they spill over — the spilling is the blessing. Cattle are bathed, painted and garlanded on Mattu Pongal. |
| Makar Sankranti | much of north and west India | 14 or 15 January | Til-gud sweets, kite-flying, bathing in rivers. |
| Lohri | Punjab, Haryana | 13 January | A bonfire at night; groundnuts, popcorn and rewri are thrown into it; bhangra and gidda are danced round it. |
| Bihu (Bohag/Rongali) | Assam | mid-April | Bihu dance and dhol; new clothes; cattle honoured on the first day. |
| Baisakhi | Punjab | 13 or 14 April | The rabi harvest is cut; fairs, processions and dancing in the fields. |
| Onam | Kerala | August–September | Pookalam flower carpets, the Onasadya feast on a banana leaf, snake-boat races. |
| Nuakhai | western Odisha | August–September | The first grain of the new rice is offered to the deity before anyone eats it. |
