Dear member,
Are you government employee? If yes, are you employed by central or state government?
Are you an employee of the private establishment? If yes, then from which state?
Rules about the closed holiday are as per the National Holidays Act of the respective state. You may refer the said act of your state to get the clarification.
Thanks,
