Sadly Outlook doesn’t support an irregular working schedule nor does it allow you to hide non-business hours.
Note: The working hours that you set in Outlook isn’t purely cosmetic; Flagged items will use it to determine when to fire reminders and the Work Week view will use it to determine which days to show (or hide).
Outlook doesn’t support irregular working days and hours.

In Outlook 2013 however, the appointments matched what date was clicked in the mini-calendar above it, and only that date. Apparently users have screamed that they wanted to see more than that, like before, so the ability to scroll ahead is back (assuming you’ve got recent free Office updates).
So now if you drag the boundary below the appointments section of the To-Do Bar down, you’ll see up to seven days’ worth of appointments.
One method that might work for you is setting Outlook’s default working days and times to your company’s main working hours and block off all the hours that you do not work with “Out of Office” appointments.
This might be time consuming and quite cumbersome but so can changing meeting invitations; it really all depends on what works best for you.
You cannot hide the non-business hours in Outlook; there is always a 24 hour calendar.
