Average Number of Unique Codes for a Given Weekday

Good day,

Looking at the attached workbook, I am looking for a way find the average number of unique codes for each weekday. In other words, on average for Fridays (Fri) there is an average of X unique codes.

I am using Excel 2019 and I don’t have access to the ‘Unique’ function.

Thank you for your help,

JF
