for example states for this year: https://www.andaman.gov.in/admin-pannel/othersdoc/1-23-Public%20Holiday%20and%20Restricted%20Holiday%202023.pdf

So:

1. It should be moved to apply to the whole of India, as it is currently missing in certain states.
2. It should be moved one day later for all years (at least 2021, 2022 and 2024 too)
3. It should be renamed from Eid ul-Fitr to Id-ul- Fitr, as this is the spelling of the Indian Goverment.

I can also provide a PR for this, once #360 is merged.
