Dear @andresaraujo,

Please accept the PR and update the code as necessary.

Thanks in advance!

[ishafiul]

already opened a pr for this! #224

[andresaraujo]

I merged @ishafiul language support for bn, if there is something needed to update in this locale can you update your PR @mortuzahossain ?

[mortuzahossain]

@ishafiul The number was still in English and there were some issues with the short message. This is why I have added this PR. @andresaraujo I have resolved these issues, and you can now merge these changes. @ishafiul Please verify these changes and feel free to make any adjustments if needed.

[ishafiul]

@mortuzahossain, I think digit mapping is important and we need this. suffixFromNow can be changed, although both are the same. Regarding প্রায়, I was confused. I thought it needs to be under users' control, whether users want to use it or not. As for short messages, I have never seen Bengali clock short form like this. please give me some reference. so that we can find a common ground.

Incorporated changes to align with @ishafiul's recommendations.

@ishafiul, please review the changes. If everything is okay, then @andresaraujo please merge the code.

Thank you.
