Adi Pooram, also known as Aadi Pooram, is a significant Tamil festival celebrated mainly in Tamil Nadu. It falls in the Tamil month of Aadi (July-August) and is dedicated to the goddess Andal, a revered figure in Tamil Vaishnavism.

The festival honours Andal, one of the twelve Alvars (saints) in the Tamil Vaishnavite tradition. She is known for her deep devotion to Lord Vishnu and her literary works, particularly the "Tiruppavai".

Adi Pooram marks the day Andal is believed to have been born. It is also the day when she is said to have adorned herself with fresh flowers and was presented to the deity. The festival is celebrated with processions, devotional singing, and elaborate rituals.

Overall, Adi Pooram is a vibrant festival that highlights the rich cultural and religious tapestry of Tamil Nadu and the profound impact of Andal's devotional poetry and life.
