Chapter 42 references both Hindu and Muslim calendar events for the day of Baba's passing. What were these corresponding dates and events?

Chapter 42 provides a synchronized view of the calendars to mark the day of Sai Baba's Mahasamadhi. From the Hindu perspective, it was the day of Vijayadashami (Dussehra) in the Shaka year 1840. The chapter also makes a finer point that the tithi of Ekadashi had begun at the moment of his departure. Concurrently, from the Muslim calendar perspective, the text records the date as the 9th day of the month, which corresponded to the night of 'Kattal', noted as the eve of Moharram. This dual reference underscores the universal nature of the event.
