When did the regular Chavadi celebrations begin, and what was the routine for Baba's sleeping arrangements?

According to Chapter 37, Sai Baba followed a consistent routine for His sleeping arrangements. He would sleep at the Chavadi every other day, alternating between one night in the Masjid and the next at the Chavadi. This sequence continued uninterrupted until His Samadhi. While this alternating schedule was a long-standing practice, the more formal worship, bhajan, and adoration as part of the Chavadi celebration officially began on December 10th, 1910. This marked the start of the grand procession and devotional gathering that became a regular feature of Shirdi life.
