According to the Satcharitra, what were the specific astronomical and calendrical details of the day Sai Baba left his body?

Chapter 42 of the Shri Sai Satcharitra provides a detailed account of the timing of Baba's Mahasamadhi. It states that his body passed away during the day in the Shaka year 1840, during the first month of the sun's southern transit (Dakshinayan). The day was Vijayadashami, which fell in the bright half of the month (Shukla Paksha). The text also notes that this corresponded to the 9th date of a Muslim month, on the night of 'Kattal' (the eve of Moharram). Preparations for his departure began in the third watch of the day.
