Bihar observes some of the most significant festivals in India, including Chhath Puja, Durga Puja, Holi, and Diwali. October is the most holiday-heavy month this year, with multiple consecutive holidays falling around Durga Puja and Chhath Puja. It is recommended that HR teams plan backup staffing and finalize leave policies well before this period.

The three national holidays — Republic Day on 26 January, Independence Day on 15 August, and Gandhi Jayanti on 2 October — are mandatory for all establishments. Regional holidays like Karpoori Thakur Jayanti, Veer Kunwar Singh Jayanti, and Vishwakarma Puja are specific to Bihar and important for state-based compliance planning.

For factories and labour-intensive businesses, May Day on 1 May carries special significance under labour law. Vishwakarma Puja in September is also widely observed in manufacturing units and workshops across the state.

If you are managing payroll or compliance for a Bihar-based establishment, keeping this holiday list handy will help you avoid errors in attendance marking, overtime calculation, and statutory filings throughout the year.
