Yama Dwitiya is observed on Dwitiya Tithi during Kartik month. Most of the times, Yama Dwitiya falls two days after Diwali Puja. Yamraj, the lord of death, is worshipped on Yama Dwitiya along with Chitragupta and Yama-Doots, the subordinates of Lord Yamraj. The Aparahna is the most suitable time for Yama Dwitiya Puja. Yamuna Snan is suggested in the morning before Yamraj Puja during Aparahna. Arghya should be given to Lord Yama after Puja.
