Navratri Parana Time : After 13:49:08
Chaitra Navratri Parana is performed on the Dashami Tithi of Chaitra Shukla Paksha (bright fortnight of the Hindu month, Chaitra). It is the day when 9-day Chaitra Navratri festival comes to an end.
Though there are contradictory statements in the Shastras to decide if the Parana must be performed on the Navami or Dashami, yet Mimansas (those who have described the Shastras) suggest to perform it on Dashami. They agreed on Dashami Tithi because one can find many texts that suggest keeping fast on Navami.
If Navami Tithi is occurring on 2 days, fast must be kept on the first day and Parana must be performed on the second day of Navami. (It is suggested by the Shastras.)
As it is the last day of Navratri Puja, Bhagwati Durga Visarjan must be performed after Shodashopchar Puja.
After Puja and Visarjan, offer food, gifts, etc. (as per your wish) to the Brahmins. Also, offer these things to the 9 little girls and perform Kanya Pujan.
We, at AstroSage, wish you a very happy Navratri!
