Festivals in Zunheboto are spectacular displays of Sumi Naga culture, heavily tied to the agricultural cycle.
* **Ahuna (November):** A post-harvest festival celebrating the year's yield. It is marked by the cooking of freshly harvested rice in bamboo tubes, accompanied by traditional singing, dancing, and feasts. * **Tuluni (July):** The most significant festival of the Sumi tribe, celebrated to mark the end of the dry season and to pray for a bountiful harvest. It involves grand community feasts, rice beer (Zutho), and cultural performances. * **Church Centenaries and Jubilees:** Given the deep religious roots of the community, church anniversaries and youth conferences are major events that draw thousands of attendees.
