Dhanteras, which is also referred to as Dhantrayodashi, is the day that inaugurates the Diwali festival, which lasts for five days. This day is considered to be one of the most fortunate days in the Hindu calendar. It is celebrated with devotion, rituals that bring prosperity, and the notion that one should invoke divine blessings in order to get wealth and well-being. Dhanteras is derived from the words "Dhan," which means "wealth," and "Teras," which means "the thirteenth day of the lunar fortnight." People celebrate Lord Dhanvantari, the divine physician, along with Goddess Lakshmi, the goddess of wealth, and Lord Kubera, the deity of treasures, on this day. Lord Dhanvantari is also worshipped on this day.
