Sandhi Puja: 48-minute ritual honouring Goddess Chamunda. Sandhi Puja occurs during the 48-minute transition between Ashtami and Navami Tithi — the last 24 minutes of Ashtami and first 24 minutes of Navami. It honours Goddess Chamunda, linked to her slaying of demons Chanda and Mund. Rituals vary by location; devotees should confirm exact timings with local temples or pandals.
