Holidays differ by company to company. The minimum number of holidays to be declared, however, will depend upon the state's Industrial Establishments (National and Festival Holidays) Act. According to the said Act there will be at least three national holidays, such as January 26th, August 15th and October 2nd. In some states rules, May day is also declared as national holiday. In addition to these there will be some festival holidays which will be decided by the company in consultation with employees/ trade unions. Festival holidays may vary from state to state and in many states there are nine such holidays.
