Hello Promsy,

Thank you for reaching out to us.

You can use our option special days. You can find it in Amelia/employee/edit employee/special days.

You can read more about this option on the following link https://wpamelia.com/configuring-schedule/

• Special Days – This feature allows you to configure one or multiple days when the employee’s schedule is somehow different from the standard one. E.g. one can have different working hours, provide different services, and/or work in a different location for one Thursday only. Whether you need to set shorter or longer working hours for just one day or a period, set a different service for one specific day or a whole week, or assign the employee to a different location for a day — here you can do all of this.
  Once you configure it, it will override the employee’s general working hours and his service schedule, but it will not override his days off.
  Click on the “Add Special Day” button and the configuration section will appear. In the “Date” option choose a date or a range of dates, then set one or multiple periods of time with working hours, choose one or multiple services for each of them in the “Service” option, and select a specific location in the “Location” option, according to what’s the special day’s setup. After you configure the special schedule, click on the “Save Special Day” button and this schedule will be applied.
  If you have services that are only provided from time to time (not on a daily or a weekly basis, but on specific occasions), this feature is a perfect match to configure such services. You can simply delete the working hours for an employee and just use the special days, so the calendar on the front-end will show the first available appointment slot. This is useful especially for services that happen from time to time. The customers won’t need to search for a date. Instead, the month with the available date will be shown right away.

Hope this helps.
