Krishna Janmashtami (Devanagari कृष्ण जन्माष्टमी kṛṣṇa janmāṣṭami), also known as Krishnashtami, Saatam Aatham, Gokulashtami, Ashtami Rohini, Srikrishna Jayanti, Sree Jayanti or sometimes merely as Janmashtami, is a Hindu festival celebrating the birth of Krishna, an avatar of the god Vishnu.
Krishna Janmashtami is observed on the Ashtami tithi, the eighth day of the dark half or Krishna Paksha of the month of Shraavana in the Hindu calendar, when the Rohini Nakshatra is ascendant. The festival always falls within mid-August to mid-September in the Gregorian calendar. In 2010, for example, the festival was celebrated on 2 September, and in 2011 on 22 August in North India and on 21 August in South Indian states like Kerala.
Rasa lila, dramatic enactments of the life of Krishna, are a special feature in regions of Mathura and Vrindavan, and regions following Vaishnavism in Manipur. While the Rasa lila re-creates the flirtatious aspects of Krishna's youthful days, the Dahi Handi celebrate God's playful and mischievous side, where teams of young men form human pyramids to reach a high-hanging pot of butter and break it. This tradition, also known as uriadi, is a major event in Tamil Nadu on Gokulashtami.
