@marwahaha ping

I also see a bunch of other languages (esp Indian) pending PR due to some extra work which needs to be done - can I clean 'em up and submit a PR?

[marwahaha]

Hi @kumarharsh - Thanks for this. If you'd like to work on other Indian languages, that sounds great.

[kumarharsh]

Updated some comments in the en-in file which were confusing. It's ready for merge I guess.

@kumarharsh Your tests are failing:

I don't know why there is a "diff" from other commits.

To be fair it differs from this one in both the AM/PM and dow/doy values... You might submit a PR with the changes, but make sure to include some proof of these claims from official sources.
