Krishna Janmashtami also known simply as Janmashtami or Gokulashtami, is an annual Hindu festival that celebrates the birth of Shree Krishna, the eighth avatar of Vishnu. It is observed according to Hindu luni-solar calendar, on the eighth day (Ashtami) of the Krishna Paksha (dark fortnight) in Shraavana of the lunar Hindu Calendar and Krishna Paksha in Bhadrapad of the lunisolar Hindu Calendar.

Dance-drama enactments of the life of Krishna according to the Bhagavata Purana (such as Rasa lila or Krishna Lila), devotional singing through the midnight when Krishna is believed to have been born, fasting (upavasa), a night vigil (jagarana), and a festival (mahotsava) on the following day are a part of the Janmashtami celebrations.
