Yes, subtracting a medium number of hours near the end of a month can shift the date into the previous month, especially if the time crosses midnight within those hours.

How many days ago is a medium number of hours in the past? โ–พ

A medium number of hours in the past typically spans several hours up to about two days ago, bridging shorter hourly gaps and full-day intervals.
