Naga Chaturthi is the festival of Snake God and it is celebrated every year on the fourth day after Diwali in the month of Karthika. Nagu means Snake and Chavithi mean the fourth day of Amavasya and it is mainly a women's festival.
Women wake up early and do a head bath without any soap or shampoo. Women will be on fasting for the whole day. This Pooja is done by women for the better health of their children and the prosperity of the family. For those who are familiar with astrology, a planet Rahu represents Snake and the effects of Raju can be rectified by worshipping the snakes.
And for those who don't know, kindly don't offer milk as Snakes don't drink milk. This should be avoided as that may lead to the death of snake and it is considered as a bad sentiment. So just do milk abishekams to Snake idols and don't burst crackers
