Both Ram’s and Krishna’s births are celebrated after 8-9 days of rituals involving purification of body and or mind.

Krishna was born exactly eight days after Raksha Bandhan as the eighth son of Devaki and Vasudeva. The eight day rituals involve eight days of mental purification starting from Raksha Bandhan where one is required to control the sexual lust. The moli or thread put on the day of Raksha Bandhan is removed only on Janmashtami and indicates learning to control the lust for the next eight days.

Ram Navami on the other hand is celebrated as a birth of Lord Rama, the consciousness after eight days of Navratre on the ninth day. Navratre is a process of purification of mind, controlling of kaama, krodha, lobha, moha and ahankara. The ritual involves living a Satvic lifestyle during Navratre period.

The era of Krishna came after Rama’s era when the love in the society was much more. Rama was in any way labeled at Maryada Purushottam.
