Patna's event calendar is deeply tied to its cultural and agricultural roots.
* **Chhath Puja:** While primarily a religious festival, it transforms the entire city into a massive community event with public gatherings at the river ghats (October/November). * **Patna Book Fair:** An annual intellectual and cultural gathering that attracts authors, publishers, and bibliophiles from across the country. * **Bihar Diwas:** Celebrated on March 22nd to commemorate the formation of the state, featuring cultural programs, food stalls, and exhibitions at Gandhi Maidan. * **Sonepur Mela:** Though located just across the river in Harihar Kshetra, this historic, month-long cattle fair deeply influences Patna's winter event landscape.
