embedded calendar showing false events

embedded calendar showing false events

My embedded calendar is displaying events in a format that causes problems. when an event stretches beyond midnight, it apparently shows up over 2 days - so for instance, because I have an event on Thursday going through 1AM Friday, I see the following when I select Friday on my embedded calendar:
7:45 AM - 1:00 AM Open
7:45 AM - 9:00 PM Open

 The top line reflects Thursday stretching to Friday, but this is not how users understand this display. Is it possible to set embedded calendars to start showing displayed events at 6am or something, to prevent this?

Thank you.
