Nag Panchami, a Hindu festival of snakes in India, is observed during monsoon season (Shravan month) and is aimed to protect and please snakes for better rains, safety and prosperity. Naga Panchami comes sometime in July-August. It is dedicated to Ananta, the serpent on whose coils Vishnu rests. Snakes are believed to have power over the monsoon rainfall and keep evil away.
Naga means snake and Panchami is the fifth day of the lunar fortnight. This festival is associated with the great serpents Adisesha or Ananta (Infinite) on whom the god rests during the intervals between the dissolutions of one universe and the creation of another.
Huge cloth effigies of the serpent are made and worshipped. Stone images of snakes are bathed in the milk and cobras are offered milk in belief that this will result in immunity from snake-bite. This festival is celebrated with religious gusto across India in the month of July/ August.
