Two day calendar view not showing enough timeslots

Working out of two offices at prestent, one with v7 and the other 8.5. In v7 I can see timeslots covering 7am to 7pm but in the v8.5 the screen view covers only 9to5.Its like the calendar screen is on steroids and all the timeslots have been bloated.

Is there a way to switch back to a v7 view of the calendar that I can access in user settings?

You should be able to set the time span in the Calendar Preferences under Calendar & To Do → Display → Views.
