Harvest festivals festivals in India
Harvest festivals are believed to be the oldest forms of festivals around the world. They are a way of thanking the nature for the bounty it offers in the form of new crops. Since India is a land of great biodiversity, different states celebrate a large number of harvest festivals. Now that the winter season is drawing to a close, it is time to reap the harvest and so is the time to celebrate. For a country largely dependent on agriculture, harvest becomes one of the most important events across the nation. Lohri, Makar Sankranti, Baisakhi, Onam, Pongal are some of them.
Harvest festivals are not just about celebrating the ripe crops but also an important astronomical change going on in the solar system. They are considered to be auspicious periods and hence are marked with celebrations and prayers.

Celebrated with a lot of joy in southern parts of India, Pongal is held for four days in January to honour mother nature. The first day is spent worshipping the God of Rain. The second day is considered to be the most auspicious day and the Pongal sweet is made by the devotees to offer to the God Sun. the third day is celebrated by honouring the cattle and on the last day, people make traditional coloured rice and enjoy the meal.
