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.
In the Rigveda, the Ādityas are the seven celestial deities, sons of Āditi,
The eighth Āditya (Mārtanda) was rejected by Aditi, thus leaving only seven sons. In the Yajurveda (Taittirīya Samhita), their number is given as eight, and the last one is believed to be Vivasvān. Hymn LXXII of the Rig Veda, Book 10, also confirms that there are nine Adityas, the eighth one being Mārtanda, who is later revived as Vivasvān. 
"So with her eight Sons Aditi went forth to meet the earlier age. She brought Mārtanda thitherward to spring to life and die again."
The Ādityas of the Rig Veda are "devas", a distinct class of gods and are different from other groups such as the Maruts, the Rbhus or the Viśve-devāḥ (although Mitra and Varuna are also associated with the latter). 
In the Bhagavata Purana, the names of 12 Adityas (Sun-Gods) are given as:
- Parjanya (Savitr?)
- Vishnu (The head of all the Adityas)
In each month of the year, it is a different Aditya (Sun-God) who shines. As Indra, Surya destroys the enemies of the gods. As Dhata, he creates living beings. As Parjanya, he showers down rain. As Tvashta, he lives in the trees and herbs. As Pusha, he makes foodgrains grow. As Aryama, he is in the wind. As Bhaga, he is in the body of all living beings. As Vivasvana, he is in fire and helps to cook food. As Vishnu, he destroys the enemies of the gods. As Amshumana, he is again in the wind. As Varuna, Surya is in the waters and As Mitra, he is in the moon and in the oceans.
The Adityas have been described in the Rig Veda as bright and pure as streams of water, free from all guile and falsehood, blameless, perfect.
This class of deities has been seen as upholding the movables and immovable Dharma. Adityas are beneficent gods who act as protectors of all beings, who are provident and guard the world of spirits and protect the world.In the form of Mitra-Varuna, the Adityas are true to the eternal Law and act as the exactors of debt.
According to the Linga Purana, the Adityas are:
- Vishnu, head of the Adityas)
Vedanta and Puranic Hinduism
- Vishnu (This Sun-God is the head of all the Adityas and is different from Lord Vishnu)
The Vedas do not identify the Ādityas and there is no classification of the thirty-three gods, except for in the Yajurveda (7.19), which says there are eleven gods in heaven (light space), eleven gods in atmosphere (intermediate space), and eleven gods in earth (observer space). In the Satapatha Brahmana, the number of Ādityas is eight in some passages, and in other texts of the same Brahmana, twelve Adityas are mentioned.  The list of 12 Adityas is as follows:
- Sanskrit version of Old Testament begins with "Adita ishvara akasham prithvi ca sasarja", meaning: In the beginning "Adita Ishvara" or "First God" created Earth and Heaven. It can be interesting thus to compare this name Adita Ishvara with Aditya - another name of Vishnu (Vamana). The same text of Genesis 1:1 in Hindi version of Old Testament says that Parameshvara (Parama Ishvara) created Earth and Heaven - and Krishna is also known as Parameshwara. Indoaryan Vedas and Zoroastrian Avesta also have common name Ahura-Mazda, which may refer to some Vedic God (sometimes on Rigveda some demigods, devatas are worshipped by name "asura", which in Zoroastrianism is Ahura-Mazda. Cyrus the Great, who was Zoroastiran, was called Messenger of Yahweh - Jewish God of Old Testament). See also: Vishnu sahasranama (Aditya: 39 aadityah, 563 aadityah - Son of Aditi)

In the later Puranic texts, all Hindu deities were referred to as Adityas. Hence, the number of Adityas increased to 33 Koties or 33 types.
