Ker Puja is a significant two-and-a-half-day festival celebrated in Tripura, a small northeastern state of India, honoring Ker, the guardian deity of Vastu Devata. Observed in early August, the festival involves strict community rituals, city-wide closures, and a ban on merriment, encouraging residents to stay at home and reflect on its cultural significance. Local businesses, including banks and government offices in Agartala, typically close during this period, emphasizing the solemn nature of the observance. Participants are urged to respect traditional practices and engage in reflection rather than commercial activities. The festival prioritizes spiritual and communal well-being, highlighting the importance of cultural heritage in the region.
