Dhanteras is the first day of Diwali or deepavali Festival as celebrated in India. The festival is basically known as “Dhanatrayodashi” where the word Dhana means wealth and Trayodashi means 13th day of the month as per Hindu calendar. On Dhanteras Hindus consider it auspicious to purchase gold or silver articles or at least one or two new utensils. It is believed that new “Dhan” or some form of precious metal is a sign of good luck.

Hindus also worship Lord Kuber as the treasurer of wealth and bestower of riches, along with Goddess Lakshmi on Dhanteras. This custom of worshiping Lakshmi and Kuber together is in prospect of doubling the benefits of such prayers.

This day is also known as “Dhanvantari Trayodashi”. Dhanvantari is an avatar of Vishnu in Hinduism. He appears in the Vedas and Puranas as the physician of the Gods (Devas), and the God of Ayurveda. People pray to Dhanvantari seeking his blessings for sound health for themselves and/or others, especially on Dhanteras. Dhanvantari emerged from the Ocean of Milk and appeared with the pot of nectar during the story of the Samudra as stated in Bhagavata Purana. It is also believed that Dhanvantari promulgated the practise of Ayurveda.
