Major Shakta temple festivals are Meenakshi Kalyanam and Ambubachi Mela. The Meenakshi Kalyanam is a part of the Chithirai Thiruvizha festival in Madurai around April/May, one of the largest festivals in South India, celebrating the wedding of Goddess Meenakshi (Parvati) and Shiva. The festival is one where both the Vaishnava and Shaiva communities join the celebrations, because Vishnu gives away his sister Parvati in marriage to Shiva. Ambubachi Mela or Ameti is a celebration of the menstruation of the Goddess, by hundreds of thousands of devotees, in a festival held in June/July (during the monsoon season) at Kamakhya Temple, Guwahati, Assam. Here the Devi is worshiped in the form of a yoni-like stone, and the site is one of Shakta Pitha or pilgrimage sites in Shaktism.
