Janaki Devi Jayanti | Sita Navami Date
Janaki Jayanti alias Sita Ashtami is specific to Krishna Paksha Ashtami which falls in the Phalgun month based upon the lunar calendar followed in the north of India. But Amanta Lunar Calendar shows Janaki Jayanti to occur during Magha. Since both fall on the same day, it does not matter how one observes Janaki Jayanti.
