What was Sai Baba's established routine for sleeping, and when did the formal Chavadi celebrations begin?

Sai Baba followed a consistent, alternating schedule for His sleeping arrangements. As Chapter 37 clarifies, Baba used to sleep at the Chavadi every other day by rule. He would spend one night in the Masjid, and the following night would be spent at the Chavadi. This sequence continued without interruption until His Samadhi. The text specifies that the formal worship, bhajan, and adoration of Sai that characterized the Chavadi celebration began later, from the 10th of December in the year 1910, adding a new dimension to this established routine.
