According to chapter 37, what was Sai Baba's sleeping schedule involving the Chavadi, and when did formal worship begin there?

Sai Baba followed a strict and continuous routine regarding his sleeping arrangements. As chapter 37 clarifies, Baba used to sleep at the Chavadi every other day by rule. One night would be spent in the Masjid, and the next would be spent at the Chavadi. This sequence was maintained continuously until His Samadhi. The same chapter also specifies that the formal worship, bhajan, and adoration of Sai at the Chavadi commenced later, starting from the 10th of December in the year 1910, marking a significant development in the devotional activities centered around the Chavadi.
