[Advaita-l] Date of ramas birth

[Kaushik Chevendra]

Namaskara sir
Recently using an astronomical software people have given shri Rama's birth
around 5000bce. They have got that date by using the descriptions of
planets and moon, season etc mentioned in ramayana. But won't this
contradict the fact that treta yuga was more than 10 lakh years ago?
Or is it possible that the descriptions of planets and moon repeat
themselves?
