Chapter 42 mentions that the day of Baba's Mahasamadhi coincided with other significant events. What were they?

The account in Chapter 42 highlights the convergence of several significant events on the day Sai Baba left his body. The primary date is identified as Vijayadashami in the Shaka year 1840. The text cross-references this with the Islamic calendar, noting it was the 9th day of the Muslim month, which is the 'night of Kattal,' the eve of Moharram. In addition to these, the chapter mentions that for some people, this same day was also observed as Buddha Jayanti. This layering of different cultural and religious observances underscores the universal significance of the day of his passing, as detailed within this chapter.
