Acquiring a detailed list of holidays across India, organized state-wise and in accordance with government directives, can be a bit of a task due to the diversity and number of holidays in different states. However, here's a step-by-step guide on how you can get this information:
1. Visit the official website of the Ministry of Personnel, Public Grievances and Pensions, Government of India. They publish a list of holidays every year which is followed by all central government offices across the country.
2. For state-specific holidays, you would need to visit the official state government websites as each state in India has the authority to decide certain holidays based on their regional and cultural significance.
3. Alternatively, you can also refer to the Reserve Bank of India's (RBI) holiday list. The RBI provides a state-wise list of holidays under the Negotiable Instruments Act. This list is usually followed by all banks, public and private organizations in the respective states.
4. For a consolidated list, there are several online platforms that provide a comprehensive list of holidays in India, state-wise. However, always cross-verify the information from these platforms with the official government sources to ensure accuracy.
Remember, the list of holidays can vary each year and it is always advisable to check the updated list at the beginning of each year from the official sources.
