this week on sunday morning may 10?

Ah, quite so, sir, the date in question is Sunday, May 10. If I may venture to say, it’s a fine day for a leisurely breakfast or perhaps a perusal of the papers. If you're asking about events or happenings on that particular morning, I would need more details to give a fuller account, but as it stands, Sunday, May 10 is simply a date in the week.
