Select Unique elements to display in the dropdown

I have a table which stores a date field and it is populated when a scheduled job is run against that row. For example a job might run today and 100 rows in the table are updated and this date field is updated to store todays date.

I have an admin dashboard where I want to display these unique dates from this table. How do I display unique dates from this table in this dropdown?
