As the screenshot below, I want to get rid of the period from 0AM to 5AM which is useless to me. How can I do that?

Go to your calendar settings and then to Laboratory tab. The lab "Hide morning and night" does what you want.

Now your calendar would only show something if you actually have something planned within that window. There is a slider to adjust the times that are hidden.

  • "The first lab" isn't going to be very helpful when Google changes what's in the Labs.

    Google has discontinued Labs. It's possible to get this feature with a Chrome Extension: webapps.stackexchange.com/a/121368/197505 Oct 15, 2018 at 15:56

Thanks to @Tschareck, we use the google calendar lab "Hide morning and night".

There is a slider to adjust the times that are hidden

which means it does NOT hide the time at first and add a slider for us to adjust the time as below screenshot.
