Bug description

Let's say I have an event that goes from 02/08/2024 00:00:00 until 04/08/2024 00:00:00. It is supposed to show as a three-days long event. Problem is that the end date shows as 03/08/2024. I have to set at least one minute at the end (04/08/2024 00:01:00) so it renders correctly. The date conversion is correct, it's translated correctly and everything else seems to work as expected. Please see the sandbox with the problem. I copy-pasted my actual running code, just stripped the typescript and commented out next navigation.

Expected Behavior

The event should render on the correct days span regardless of the end time (hours, minutes, seconds).

Actual Behavior

It doesnt show the correct days span if the end time is something between 00:00:00 and 00:00:59.
