Chapter 42 mentions several calendrical and astrological details surrounding Baba's Mahasamadhi. Can you elaborate on these specific timings?

Certainly. Chapter 42 meticulously records the timing of Sai Baba's departure by aligning multiple calendar systems. It states the event occurred in the Shaka year 1840 on Vijayadashami, a significant day in the Hindu calendar also known as Dussehra. This day fell during the 'Dakshinayan' period, the sun's southern transit. The chapter notes a convergence with the Islamic calendar, specifying it was the 9th day of the month of Moharram, the eve of 'Kattal'. It also clarifies a nuance regarding the lunar days (tithis), noting that while the bell struck at twelve-thirty and the Dashami period was completed, Ekadashi was dawning, making the time of departure technically Ekadashi.
