Calendar issues

The google calendar shows the ENTIRE day. Maybe it's just me, but I rarely need to schedule anything after 9 PM and before 7 AM. First question: Is there a way to make it so I don't have to scroll through 9 PM to 7 AM? Second question: When I tried to download an app called agenda widget that I thought might fix the problem it was blocked because it wasn't from the official site. Fine. So is there an app that solves my problem that is available from the official site?
