According to the source material, can you provide the specific date and time of Sai Baba's Mahasamadhi?

Chapter 42 provides very specific details about the timing of Sai Baba's departure from his physical form. The event took place in the Shaka year 1840, during the first month of the sun's southern transit (Dakshinayan). The Hindu lunar calendar day was Vijayadashami in the bright half of the month (Shukla Paksha). The chapter also correlates this with the Muslim calendar, noting it was the 9th date, corresponding to the eve of Moharram, known as the night of 'Kattal'. The text specifies that Sainath began preparations for his final departure during the third watch of the day, giving a precise timeline for this momentous occasion.
