Even when banks are closed physically, you can still carry out most tasks using internet banking, UPI, ATMs, and mobile apps. These services are available round the clock, including holidays.
Do note: banks are closed on Sundays, 2nd and 4th Saturdays, and national or gazetted holidays. Local holidays can differ by city or state — for example, banks might be open in Delhi but closed in Kerala due to a state-specific festival.
To avoid inconvenience, check the Reserve Bank of India holiday calendar or your bank’s official site to confirm the status in your region.
