How does Chapter 42 connect the day of Sai Baba's Mahasamadhi to both the Hindu and Muslim calendars?

Chapter 42 of the Shri Sai Satcharitra bridges the Hindu and Muslim calendars when describing the day of Sai Baba's passing, reflecting his universal appeal. According to the Hindu calendar, the text specifies the date as Vijayadashami in the Shaka year 1840, during the bright half of the month. Simultaneously, Chapter 42 links this to the Muslim calendar by stating it was the 9th date of the Muslim month. It further adds that the night was the 'Kattal,' which is identified as the eve of Moharram. This dual dating in the narrative underscores how Baba was revered across different religious communities.
