Type of bank holidays
There are certain bank holidays that are state-specific and some where banks throughout the country are shut. Major all-India holidays include Republic Day on January 26 (Tuesday), Idul Fitr on May 13 or May 14 (Tuesday or Wednesday, depending on the state) and November 4 for Diwali (Thursday).
Then there are holidays where banks across many states will be shut. These include Good Friday, Baisakhi/Vishu/Biju Festival/Cheiraoba/Bohag Bihu, Muharram, and Durga Puja or Dusshera.
State governments decide specific holidays. For instance, in Kerala, state-specific holidays include Onam and Vishu.
Banks also remain shut on the second and fourth Saturdays of the month.
