Chapter 42 mentions several different calendar and time references for Baba's passing. Can you explain the different tithis and dates mentioned?

Chapter 42 meticulously documents the timing of Sai Baba's Mahasamadhi using multiple calendar systems to provide a complete picture. The source states it occurred on Vijayadashami, a significant Hindu festival day. This same day corresponded to the 9th date of the Muslim month, known as the night of 'Kattal' (the eve of Moharram). The chapter clarifies a point about the lunar days (tithis), noting that Baba passed away around twelve-thirty in the afternoon. At this specific time, the Dashami tithi had just completed, and the Ekadashi tithi had begun, making the precise time of departure fall on Ekadashi, even though the day is remembered as Dussehra.
