According to Chapter 42, can you provide the specific details regarding the date and time of Sai Baba's Mahasamadhi?

Chapter 42 provides precise details about the timing of Sai Baba's passing. It occurred in the Shaka year 1840, during the first month of the sun's southern transit (Dakshinayan). The specific day was Vijayadashami in the bright half of the month (Shukla Paksha), which also corresponded to the 9th day of the Muslim month, the eve of Moharram known as 'Kattal'. The text further clarifies that the departure took place in the third watch of the day. While the bell struck twelve-thirty, completing the Dashami period, Chapter 42 notes that Ekadashi had dawned, and thus the actual time of departure was during the Ekadashi tithi.
