Diwali celebrations begin with Dhanteras on the thirteenth day of the Kartik month, Krishna Paksha (waning phase of the Moon). Chhoti Diwali traditionally referred to as Naraka Chaturdashi is observed on the following day to celebrate the triumph of Lord Krishna's consort, Satyabhama over Narakasura.
On this day, people take a holy bath in the morning called Abhyanga Snan. It is a ritual that symbolises the cleansing of the mind and the body. This year, Naraka Chaturdashi or Chhoti Diwali will be celebrated on November 14. The sacred timing for rituals (shubh muhurat) is between 5:23 AM to 6:43 AM.
Some people are celebrating Chhoti Diwali today, i.e, on 13 November and Dhanteras on the previous day.
