Dhantrayodashi or simply Dhanteras is the first significant day of Diwali festival. 'Dhan' means wealth and 'Teras' signifies the thirteenth day in the moon cycle. This festival of wealth falls in the month of Kartika on the thirteenth day of Kartik Krishna Paksha. It usually occurs one or two days before the main Diwali Puja Day, also known as Lakshmi Puja. Dhanteras is also known as Yamadeepdaan and lamps are kept burning through the night in reverential adoration to Yama - and prayers offered to him to keep away death and despair.
