How to display time slot duration by hour on the calendar

When I click on my accounts → calendar, this is what it looks like. How do I make it so that it looks better? Specifically, I want every hour of the day only. E.g. 8-9am, 9-10am, 10am-11am, etc.

Hi,

The calendar grid depends on the time frame set in the listing settings and the selected duration slot. If the slot is from 00 to 00 and 60 minutes, there will be 24 slots.
