Krishna is Devaki and Vasudeva Anakadundubhi's son and his birthday is celebrated by Hindus as Janmashtami, particularly those of the Gaudiya Vaishnavism tradition as he is considered the Supreme Personality of Godhead. Statue of Krishna being carried across the river Krishna Janmashtami is followed by the festival Nandotsav, which celebrates the occasion when Nanda Baba distributed gifts to the community in honor of the birth. It is celebrated particularly in Mathura and Vrindavan, along with major Vaishnava and non-sectarian communities found in Manipur, Assam, Bihar, West Bengal, Odisha, Madhya Pradesh, Rajasthan, Gujarat, Maharashtra, Karnataka, Kerala, Andra Pradesh, Tamil Nadu and all the other states of India. 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 was born, fasting ( upavasa), a night vigil (Ratri Jagaran), and a festival (Mahotsav) on the following day are a part of the Janmashtami celebrations. It is an important festival, particularly in the Vaishnavism tradition of Hinduism. This overlaps with August or September of the Gregorian calendar. According to Hindu lunisolar calendar, it is observed on the eighth tithi ( Ashtami) of the Krishna Paksha (dark fortnight) in Bhadrapada Masa. Krishna Janmashtami, also known simply as Janmashtami or Gokulashtami, is an annual Hindu festival that celebrates the birth of Krishna, the eighth avatar of Vishnu.
