A schedule is available for each store in an account.
You can select a date to add an event, or click on the top right button 'Add an event'. An event can be linked to a user or a table/resource (booking for restaurants).
You can setup the Schedule tab as your default page on your account (in Settings/Users/Users), and you can open a sale directly from an event.
In the settings of the schedule, you can show only the opening hours, set a default event duration or display events by resource.
