How can I show just busines hours on my calendar?

[DragonFly145]

The calendar shows 24 hours.   It is not efficient and it can be dangerous in my case.  The other day I mistakenly opened my calendar for 4am and not 4pm.   Is there a way to change this?  I'd just like to show 8am-9pm.

Did you set yourself as a staff member and then select the hours you are available for booking?
