Saikumar,
In my response to the above query, I didn't gave any reference of Factories Act, 1948. All I said was that there are THREE holidays that are compulsory (26th January, 15th August and 2nd October) for all the companies and industries across India. Other holidays are choosen by companies based on state of their operations. In fact, if one company is having offices in different states, they can choose different list of holidays.
Thanks,
Sanjeev
