Janmashtami is a Hindu festival celebrated to mark the birth of Lord Krishna, one of the most revered deities in Hinduism. It falls on the eighth day (Ashtami) of the Krishna Paksha (dark fortnight) in the month of Bhadrapada according to the Hindu lunar calendar, which usually corresponds to August or September in the Gregorian calendar.

Lord Krishna is considered the eighth avatar (incarnation) of Lord Vishnu, and his birth is believed to have taken place in Mathura, a city in present-day Uttar Pradesh, India. Janmashtami is celebrated with great enthusiasm and devotion across India and by Hindu communities around the world.
