@prashanttholia - sorry for not replying sooner. We discussed this and felt it would be better to go with the Y formatting character rather than r. I know that you are keen to help out in this but since we are really close to final release of 11.0.0, @AndrewKushnir went ahead and created a PR to fix this up in https://github.com/angular/angular/pull/39495. Thank you for the original PR.

(We need to work out what to do about ISO alignment for weeks etc too.)

(Also thanks to @cexbrayat for pinging me about this outstanding question!)

@prashant-tholia - great! Please make sure you have read https://github.com/angular/angular/blob/master/CONTRIBUTING.md. The PR will need to include unit tests and documentation before it can be merged.

Let me know if you need help getting started.
