Set the default display interval to determine how vertical lines appear on the appointment book or calendar. This setting affects only the calendar view and does not change the available booking slots, so appointments can still be scheduled at shorter intervals.
At the organization level, click the Configuration icon.
Search for and select Set default display interval in the appointment book.
For example, if the business sets the default display interval to 15 minutes and the appointment slot interval to 5 minutes, the calendar will show intervals as 10:00, 10:15, 10:30, 10:45, and so on. However, guests can still book appointments at 5-minute intervals, such as 10:20.
Enable this setting.
Click Save.
Disable this setting if you do not want to see display intervals in the appointment book.
