Nag Panchami is observed on Shrawan Shukla Paksha Panchami during Sawan month. Usually, Nag Panchami day falls on the second week or the last week of the month of Shrawan July/August. This year Nagpanchmi is on August 21.

Annually, local people visit Nag Pokharaki Naxal, Nagdhaha in Dhapakhel,6 kilometers from Langankhel, to worship nag.

According to the Hindu calendar, the festival of Nag Panchami is celebrated on the Shukla Panchami date of the month of Shrawan. According to religious beliefs, the snake deity, the ornament of Lord Shiva, is worshiped on this day. Worshiping serpents on this day removes the troubles of life. This time the festival of Nag Panchami is celebrated on Friday, 13th August.

According to normal human nature, we get excited as soon as we see a snake, because our belief has been that a snake bites. Therefore, when we see a snake, we are ready to kill it. This is a very wrong idea. Of all the snake species in the world, only a very small number of snakes are venomous. Most snakes are non-venomous. The malice that awakens in us when we see a snake is the cause of the malice that is created in a snake, so there is a proverb that "a snake does not bite if it does not bite". There is no doubt that snakes need to be worshiped and protected as they play an important role in our agriculture and forest resources.

Science says it is dangerous to feed snakes: According to science, snakes are not mammals, so they should not be fed milk. Reptiles cannot digest milk, and in such cases, many times they die. Milking a snake can infect it and eventually kill it.

Nepali people worship snake gods, also called the Nagas during Nag Panchami. In ancient times, Nagas halted rain from pouring over Nepal. The king of that time also happened to be a Tantric and so he used his power to make Nagas let go of rain. The king succeeded in doing so but he also honored the majestic power of Nagas by turning the day of victory into a festive occasion of Nag Panchami. On Nag Panchami, devotees put a picture of Naga high above their doorway and perform puja with necessary puja items. Offerings in the form of food are left in the yards and paddies for snakes. Naga temples in the valley at Nagpokhari, Taudaha and Nagdaha are thronged with devotees on this day.

During Nagpanchami people wake up early in the morning and take bath with precious water then make images of the serpent /Nag, Ganesh, and Kalash with cow dunk or white flour and worship. It is customary to visit serenely Naga’s, Pound, well and Shiva temple and worship Serpent offering cow milk, sesame, barley, Doobo and Kush (sacred grass) and burning Shrikhand (sandalwood) incense. It is said that the aroma of Shrikhand is the dearest thing of Nagadevata/Serpent. If we go to the nearby tree of Shrikhand, be too careful with the serpent.

Similarly, in this Puja (worship), there is a law to use white lotus flowers and Lava (parched paddy that is grown in the flower). Likewise, people draw the picture of Serpents and past on main entrance of the house/door, offer Yogurt, Dubo, Kush, Sindur (a traditional vermilion red or orange-red colored cosmetic powder), Chandan, etc. for worship. People believe that there is no lighting in the house, no fear of firing and snakes and other poisonous species from the worship of Nag on this day. This day is believed to have started the winter with the end of the rainy season.

Women worship Nag Devta and offer milk to snakes on this day. Women also pray for the wellness of their brothers and family.
