It's some time since I saw it but IIRC this is not set in a single day but over a couple of days
Groundhog Day obviously.....all in one day over and over again

It's set over a 24 hour period commencing and finishing at night. This is probably why you think you are remembering two days. You are in fact remembering two nights, but those two nights, the intervening day, and their events all occur within a 24 hour period.
