Answer:

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.[3] It is observed according to the Hindu lunisolar CALENDAR, on the eighth day (Ashtami) of the Krishna Paksha (dark fortnight) in Bhadrapada, which overlaps with August or September of the Gregorian calendar.[3]

It is an important festival, particularly in the Vaishnavism tradition of Hinduism.[4] 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.[5] 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.[3][6]

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.[7]
