Durga Visarjan is a ritual performed at a specific time, which can be either during Aparahna or Pratahkala while Dashami Tithi is prevailing. In most of the time, Visarjan Muhurat occurs during morning, however, if both Shravana Nakshatra and Dashami Tithi together prevail during Aparahna, then Aparahna Muhurat should be given preference over morning Muhurat.
Usually after the Durga Visarjan ritual, people break nine days Navratri fasting. Hence Durga Visarjan timing can also be considered for Navratri Parana.
