Kharchi Puja is one of the most important festivals in Tripura, celebrated in July in the capital city of Agartala. The festival is dedicated to the worship of the 14 deities of the state, believed to cleanse the sins and purify the spirits of the devotees. The deities are brought out of the temple and bathed in the holy water of the Howrah River. The festival lasts for seven days and includes various rituals, cultural performances, fairs, and community feasts.

Celebrated in April, Garia Puja is a traditional tribal festival of Tripura dedicated to the worship of the deity Baba Garia. It is primarily celebrated by the indigenous tribes like the Tripuri, Jamatia, and Reang to pray for a good harvest, health, and prosperity. The festival involves rituals such as the sacrifice of a cock, traditional dance performances, and the singing of folk songs. People also enjoy a traditional bamboo dance called "Lebang Boomani."

While Durga Puja is celebrated throughout India, it holds special significance in Tripura, especially among the Bengali community. The festival, celebrated in September or October, marks the victory of Goddess Durga over the demon Mahishasura. It is characterized by elaborate decorations, idol processions, cultural programs, and community feasts. The entire state comes alive with vibrant decorations, lights, and festive fervour during this period.
