Filter to only show duplicates

[Alfred54]

How can I show only duplicate entries by removing the first or unique entries.
The list needs to be also date specific so it only shows duplicates with the same date.
The required rows have an asterix *

Use a formula similar to this =COUNTIFS($A$2:$A2;A2;$B$2:$B2;B2)>1 in the additional auxiliary column
