The Election Commission of India has announced the complete schedule for the 2025 Bihar Assembly elections on Monday (Oct 6, 2025), where elections for all 243 assembly seats will be conducted in two phases for the first time in history. Polling for the first phase of 121 constituencies is scheduled for 6 November, while the second phase will be held on 11 November for the remaining 122 seats. The counting of votes and results will be announced on 14 November.&nbsp;This Assembly election will decide whether Nitish Kumar-led NDA will retain power in Bihar or RJD will return to the helm of the government for the first time in 20 years, along with its allies or the newly formed Jan Suraaj party, led by Prashant Kishor, could make a full surprise.
