I have traversed all of the self-help provided, yet I cannot find out how to
remove hours such as 11:00 pm through 4:00 am from view in my work calendar.
These hours take up unnecessary space on my weekly calendar view; thus, I
would like to restructure my daily calendar such that it extends from only
6:00 am until 10:00 pm. I already know how to change the shading to
differentiate between work and non-work hours--this is insufficient.

Any insight?
