Can we ask someone "What did you do yesterday since morning till noon?"

Please check.

Or say it more simply: "What did you do yesterday morning?"

"Morning," by definition, ends at noon.

I can see where casually what you do before lunch is your "morning."

But whereas "evening" can be a flexible timing, "morning" ends when "afternoon" begins. And afternoon is taken literally.

It would be bizarre for an American to refer to any time after twelve noon as "morning". Interesting that the term may be shifting towards a functional rather than precise meaning in BrE.

I'm with the clock-watchers on this one. I stop saying "Good morning" at 12 noon. At that point, I switch to "Good afternoon". When I eat lunch doesn't factor into it.

A common little incident in American life is to hear one's interlocutor make a correction after noticing it's two minutes past noon: ​Good morning - I mean, afternoon.

Or exchanging pleasantries when you start a conference call where it's 11 AM on one end and 12PM on the other.
