Almost each and every Hindu festival is dedicated to the Avatar of either god Vishnu or God Shiv but Radha Ashtami or Radhastami is celebrated for Radha also known as Radharani ( Queen of Vrindavana ). Radha Rani was born in Barsana, Uttar Pradesh, India and she was the closest friend and most loved devotee of Shri Krishna. Radha Ashtami is celebrated in the Ashtami tithi during Shukla Paksha. The devotees on this day do fasting and pray Radha Rani with Shir Krishna and recite Krishna Katha
