Ram Navami is celebrated to proclaim the birth of Lord Sriram, the seventh incarnation of Lord Vishnu. The 9th day (Navami) in the bright fortnight of the Hindu lunar month of Chaitra is referred to as Ram Navami. On this day, when the five planets and the sun, etc. were in the first house of cancer at noon along with the lunar asterism Pushya, Ramachandra was born in Ayodhya. Several temples of Shriram celebrate this festival for nine days beginning from the first day (pratipada) of Chaitra. It is celebrated by periodic readings (parayans) of the Ramayan, organising spiritual discourses (kirtans) and beautifully embellishing Shriram's idol. On the ninth day, in the afternoon, a spiritual discourse on Shriram's birth is held. At noon, a coconut draped in a hooded cloak is placed in a cradle and the cradle is rocked. Devotees shower a red, fragrant powder (gulal) and flowers onto it.
Ram Navami Celebrations start on Gudi padwa, the first day of Chaitra; and continue for 9 days. During this period, devotees do parayans of Ramayan, recite the Ramaraksha stotra, sing bhajans-kirtans in His praise and chant His name.
In the epic Ramayana, Dasharatha, the Emperor from Ayodhya, had three wives named Kausalya, Sumitra and Kaikeyi in the Treta Yuga, which follows the Satya Yuga and is succeeded by Dwapara Yuga. Their greatest worry was that they had no children, and so they had no heir to the throne in the Ikshvaku Kula or royal lineage of great, pious, wonderful Emperors. Rishi Vasistha suggests him to perform Puthra Kamesti Yagna, through which he can have a desired child. He also tells him to invite Maharshi Rishyasringa to perform this yagna for him. Emperor Dasharatha consents and heads to Maharshi Rishyasringa's ashram, to invite him. Maharshi agrees and accompanies Emperor Dasharatha to Ayodhya (Capital of Avadha) and performs the yagna. As the result of this yagna, Yagneshwara appears and provides Dasharatha a bowl of divine pudding (Kheer/Payasam) and requests him to give it to his wives. Dasharatha gives one half of the payasam to his elder wife Kausalya, and another half to his younger wife Kaikeyi. They both give half of their portions to Sumitra. After few days all three Queens conceive. On the ninth day (Navami) of Chaithra Masa (last month in Vedic calendar), at noon Kausalya gives birth to Rama, Kaikeyi gives birth to Bharata, and Sumitra to twin boys, Lakshmana and Shatrughna.
Rama is the seventh incarnation of Vishnu, who takes birth by His own will, on Bhuloka (Earth) when Adharma rules over Dharma. He protects all his devotees by vanquishing the roots of Adharma. Rama decided to incarnate to destroy an Asura or person with demonic and evil designs, called Ravana.
