Govardhan Puja is also known as Annakut Puja. On this day, Hindus prepare and offer a wide variety of delicacies to the idols of God to express their gratitude. This year, Govardhan Puja is falling on Sunday, November 15, 2020. Devotees offer a mountain of food, representing the Govardhan Hill. Annakut is celebrated on the fourth day of Diwali. The fourth day of Diwali is also the first day of the new year in the Vikram Samvat calendar. Also called Vishvakarma Day-- some craftsmen pay reverence to their tools and machinery on this day.
This day is commemorated as the day when Lord Krishna defeated God Indra. As described in the Bhagavata Purana, Govardhan Puja is chiefly identified with Lord Krishna lifting the 'Govardhan Hill' on his finger to protect those who sought his refuge from Indra's torrential rage
In Maharashtra, it is celebrated as Bali Pratipada or Bali Padva. The day commemorates the victory of Vamana, an incarnation of Lord Vishnu, over King Bali and subsequent pushing of Bali to Patal Lok. It is believed that due to boon given by Lord Vamana, Asura King Bali visits the Prithvi Lok from the Patala Lok on this day.
