Hanuman was born to Anjana Devi, a female vanara, and Kesari, a male vanara, in Anjana Giri mountain.
His mother was an apsara who was born on Earth as a female vanara due to a curse. She would be redeemed from this curse on her giving birth to an incarnation of Lord Shiva, who is also known as Rudra, and endowed with the Supreme Power of exalted devotion to Bhagwan Hari.

Hanuman is endowed with 28 transcendental divine opulences, with perfection in each.

Anjana, along with her husband Kesari, performed intense prayers to Lord Shiva to beget Him as her Child. Pleased with their devotion, Shiva granted them the boon they sought.Hence, Hanuman is also known as "Maharudra" because he was born of the boon given to Anjana by Shiva.

The Valmiki Ramayana states that Kesari is the son of Brihaspati king of a region named Sumeru, located near the kingdom of Kishkindha.
Kesari also fought on Rama's side in the war against Ravana.

Hanuman is also known as the son of Vayu, the wind-god.

When Anjana was worshiping Rudra, King Dasharatha of Ayodhya was also performing the ritual of Putrakameshti in order to have children. As a result, he received some sacred pudding (payasam) to be shared by his three wives, leading to the births of Rama, Lakshmana, Bharata, and Shatrughna. By divine ordinance, a kite snatched a fragment of that pudding and dropped it while flying over the forest where Anjana was engaged in worship. Vayu, delivered the falling pudding to the outstretched hands of Anjana, who consumed it. Hanuman was born to her as a result.
His ability to fly like a bird is due to this.

Hanuman is worshipped to attain victory against evil and Adharma
and On this festival, devotees of Hanuman celebrate him and seek his protection and blessings.
Devotees join in temples to worship him and present religious offerings. In return, the devotees receive prasadam by the temple priests as sweets, flowers, coconuts, tilaka, sacred ash (udi) and Ganga jalam (holy water). People who revere him also recite various devotional hymns and prayers like the Hanuman Chalisa and reading holy scriptures like the Ramayana and Mahabharata.
