Can you provide the specific details about the date and time of Sai Baba's Mahasamadhi as recorded in Chapter 42?

Certainly. Chapter 42 provides precise details regarding Sai Baba's departure from his physical body. It states that this event occurred in the Shaka year 1840, during the sun's southern transit (Dakshinayan). The specific day was Vijayadashami in the bright half of the month, which coincided with the 9th day of the Muslim month, the eve of Moharram. The text further specifies that Sainath made preparations for his departure during the third watch of the day. The time is noted as twelve-thirty, when the Dashami tithi completed and Ekadashi began, establishing the precise moment of his passing.
