Are universities typically ok with applications being submitted about an hour late?

I’m just curious and a bit worried. If I were to submit my app at 1 am instead of before 12 am on the day of, would there be a substantial chance that they won’t consider my application? The university in question is UMich lol

EDIT: I emailed UMich to check. They said they “may consider applications submitted shortly after the February 1st deadline on a space-available basis.”
