The plugin has an option known as Order Processing Time. The main purpose of this option is to define the time it will take to manufacture/prepare/pack the order. With the help of Business Days, you can easily define the days and hours your team will be available for manufacturing/preparing/packing the order.
The settings for setting up the Business Days can be found at Delivery and Pickup Scheduler > Settings > Order Local Pickup > General > Business Day.
By default, all the 7 days of the week will be enabled and the Opening Time and Closing Time will be set as 09:00 AM and 06:00 PM Respectively.
You can customize the Working Days and Hours of your team based on your preference. If you wish to disable a Day, just uncheck the checkbox which is available before the Day and save the settings.
