In Hinduism, Ādityas, meaning "of Aditi", refers to the offspring of Aditi. The name, Aditya, is used in the singular to mean the Sun God, Surya.
The Bhagavata Purana lists a total of twelve Adityas as Sun-gods. In each month of the year a different Aditya is said to shine. Each of these Adityas is a different expression of Lord Vishnu in the form of the Sun-God.
