This way a number of commands could be removed. As well as the m.dy indicator that's so annoying for the users beyond the big pond, or the y.md for those in the Far East. A calculator solely based on internationally agreed standards - wouldn't this be a great idea?

The date indicator is not shown if Y register display is enabled (it wouldn't fit on the screen). There's also a compile time option to disable it statically and it wouldn't be difficult to make it a run-time option if needed (although it would increase the size of the firmware).

I use yyyy-mm-dd everywhere because in my opinion that's the only format that really makes sense, and I agree it'd be a good default, but by removing the other options we'd inconvenience very many (if not most) users in order to save a tiny bit of firmware or catalog space. I don't think it's a good idea. International standards should be promoted through leading by example and making them easy to use, not by restricting choice.
