For the google calendar website GUI, the default time is from 00:00 to 24:00. However, normally 00:00 to 8:00 is useless to both me and most people. It annoys me a lot by scrolling down each time to the time after 8:00. Is it possible to disable 00:00 to 8:00? Outlook does it by starting a default day calendar at 8:00, which is set by user. People just scrolls up to see schedules before 8:00 if necessary. It is a good idea, and I wonder can I do it at google calendar?
