    Good day ebersolorzano. The function you need is available from Power Query's UI, via the "Remove Rows" button. Select the columns which are to be considered for duplication. Click "Remove Rows" and from the sub-menu which pops up click "Remove Duplicates". 

     

    The Power Query documentation on removing duplicates is here and the "BI Gorilla" has a complete guide here.

     

    I reproduced your data, brought it into Power Query...

    and then applied the solution to give...

    The M code is...

    = Table.Distinct(#"Name of Previous Step", {"Name", "Year", "Month", "Day"})

     ...the columns being considered in the duplication are listed between the curly brackets.
