Chapter 42 mentions several different calendars and observances related to the day Sai Baba left his body. What were they, and how did they align?

Chapter 42 meticulously documents the day of Sai Baba's Mahasamadhi by referencing multiple calendars and observances to mark its significance. According to the Hindu lunar calendar, the event took place on Vijayadashami in the bright half of the month (Shukla Paksha), though the chapter clarifies the time of departure was actually during the Ekadashi tithi which had just begun. The solar calendar context is given as the Shaka year 1840, in the first month of Dakshinayan. As mentioned in Chapter 42, this day also coincided with the 9th date of the Muslim month, the eve of Moharram, known as the night of 'Kattal'. Furthermore, the text notes that for some, this same day was observed as Buddha Jayanti.
