Did the last day of Moses start in Deuteronomy 9:1?

I think so. Deuteronomy 9:

1 “Hear, O Israel: you are to cross over the Jordan today, to go in to dispossess nations greater and mightier than you, cities great and fortified up to heaven."

That's a long day for Moses. His speech continues till Deut 33, the penultimate chapter.
