Nepali people celebrate Dashain, also known as Vijaya Dashami, as one of the most significant festivals of the year. It is a celebration of the triumph of good over evil, rooted in Hindu mythology.

Many historians believe Dashain became widespread in Nepal around the time of the Malla Dynasty (12th to 18th century), when Hinduism became prominent in the Kathmandu Valley, though it could date even further back, given its connection to ancient Hindu scriptures.
