Before Change

            columns to be merged on.  The values from df1 are the ones which
            are retained for any shared, non-merging columns.
    
    if year_col not in df1.columns:
        assert date_col in df1.columns
        assert date_col not in df2.columns
        df1[year_col] = pd.to_datetime(df1[date_col]).dt.year

    if year_col not in df2.columns:

        assert date_col not in df1.columns

After Change

    // assert df_date[date_col] is a Date
    // assert df_year[year_col] is a Date
    df_date = df_date.copy()
