Business Day And Non Business Day

A business day is any day on which banks, stock exchanges, and financial institutions are open and operating normally — typically Monday through Friday, excluding nationally declared public holidays. In Indian capital markets, business days for NSE and BSE are defined by the exchange holiday calendar published annually — excluding national holidays (Republic Day, Independence Day, Gandhi Jayanti), gazetted holidays (Diwali, Holi, Eid, Christmas, Gurunanak Jayanti), and any special market closures declared by the exchange or SEBI. A non-business day (or bank holiday) is any day on which financial institutions are closed — including Sundays, national holidays, state-specific holidays (for banks in states observing local holidays), and any other designated non-working days. The distinction between business and non-business days is critical in Indian financial markets for: calculating settlement timelines (T+1 means the next business day, not the next calendar day), determining interest accrual on borrowings, computing notice periods for loan repayment and margin calls, and setting deadlines for IPO applications and allotment processes. For corporate bond and fixed deposit investors, coupon payment and maturity value settlement delayed by a non-business day are typically paid on the immediately following business day — this accrual and payment convention is specified in the bond's terms. For derivatives traders, awareness of exchange holiday calendars is essential for accurately planning option exercise strategies and futures rollover timing.
