Janmashtami is an annual Hindu festival that celebrates the birth of 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, which overlaps with August and September of the Gregorian calendar.
It is an important festival particularly to the Vaishnavism tradition of Hinduism. 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 (mahotsava) on the following day are a part of the Janmashtami celebrations.
It is celebrated particularly in Mathura and Vrindavan, along with major Vaishnava and non-sectarian communities found in Manipur, Assam, West Bengal, Odisha, Madhya Pradesh, Rajasthan, Gujarat, Maharashtra, Karnataka, Kerala, Tamil Nadu, Andhra Pradesh and all other states of India.
This year Janmashtmi is on Saturday 24th August.
