- The first day (November 12, 2020) is known as Dhanteras, or Dhanatrayodashi. "Dhan" means wealth and "teras" refers to the 13th day of a lunar fortnight on the Hindu calendar. Lord Dhanvantari, the Hindu god of medicine and an incarnation of Lord Vishnu, is said to have brought Ayurveda and the nectar of immortality to mankind on this day. There are a number of temples in Kerala and Tamil Nadu dedicated to Dhanvantari and Ayurveda. Legend also has it that Goddess Lakshmi was born from the churning of the ocean on this day, and she is welcomed with a special puja (ritual). Gold and other metals (including kitchen utensils) are traditionally purchased. People also gather to play cards and gamble, as it's thought to be auspicious and will bring wealth throughout the year.
