When did the formal worship and celebrations at the Chavadi begin, and what was Baba's established routine involving that place?

The source material in Chapter 37 specifies the exact date when formal worship began at the Chavadi. The practice of worship, bhajan, and adoration of Sai at the Chavadi commenced on December 10th, 1910. Beyond these celebrations, Sai Baba had a consistent and unbreakable routine where he would sleep at the Chavadi every other day. He would spend one night in the Masjid and the very next night at the Chavadi. This sequence continued without a break right up until His Samadhi, demonstrating the Chavadi's integral place in His life.
