The event calendar in Korba is marked by a blend of religious, cultural, and local administrative festivals.
* **Korba Mahotsav**: A major annual cultural festival organized by the district administration, featuring folk performances, musical concerts, and exhibitions of local arts and crafts. * **Navratri and Durga Puja**: Celebrated with grand *pandals* (temporary shrines) and vibrant processions across the city. * **Madai Melas**: Traditional tribal fairs held in the winter months in the rural outskirts, serving as both a cultural gathering and a marketplace for local communities. * **Chhath Puja**: Due to a large migrant workforce from Bihar and Uttar Pradesh, Chhath Puja is celebrated on a massive scale along the banks of the Hasdeo River.
