The day preceding Diwali is celebrated as Naraka Chaturdashi, which is also called Choti Diwali or Kali Chaudas. It is celebrated in recognition of the victory of morality over evil, as illustrated by the demon Narakasura being vanquished by Lord Krishna. Due to its emphasis on banishing evil spirits and welcoming good ones, the event is highly significant from a spiritual and astrological perspective.
