Hindus have an ancient tradition of worshipping snakes and serpents, denominated Naga Panchami. It is celebrated in every country where Hindus reside. It habitually occurs on the fifth day of the Shravana month, which covers the period of July and August on the Gregorian calendar. According to the Hindu culture, snakes and serpents dwell in the realms of the netherworld, which in Indian religions is known as the patala loka. The patala loka comprises seven regions, the lowest of which is called Naga-loka. Hindus worship the snakes for their belief that they endow blessings and prosperity upon families. The day is usually observed by laving the serpent deities in milk, which are then venerated.
