The traditional hagiographies of Ramanuja state he was born to mother Kānthimathi and father Asuri Kesava Somayāji, in Sriperumbudur, near modern Chennai, Tamil Nādu. He is believed to have been born in the month of Chaitra under the star Tiruvadhirai. They place his life in the period of 1017–1137 CE, yielding a lifespan of 120 years. These dates have been questioned by modern scholarship, based on temple records and regional literature of 11th- and 12th-century outside the Sri Vaishnava tradition, and modern era scholars suggest that Ramanuja may have lived in 1077–1157 CE.
