Today, 9 August 2013 is Aadi Pooram, Andal Jayanti. It is celebrated widely in Tamil Nadu and some parts of Kerala and Karnataka. The Pooram Nakshatram day in Aadi month is also celebrated as Andal Jayanti.
Andal Ammal is believed as the incarnation of Goddess Shakti Devi. In 2013, it is even more auspicious as it falls on Friday as Aadi Velli (Friday in Aadi masam) is dedicated to Sakti Ammal.
Aadi Pooram is one of the big festivals at Madurai Meenakshi Amman Temple, Melmaruvathur Adhi Parasakthi Temple, Srivilliputtur Andal Temple, Tiruneveli temple, Vedaranyam temple, and many other Sakti Amman temples in Tamil Nadu.
