Power BI DAX，月末不适用于日期表

Question

When using endofmonth dax statement with my fact table it works:

EOM = 
CALCULATE(
    SUM('Table'[sales]),
    ENDOFMONTH('Table'[date])
)

However when I use it with my date table it returns blanks does anyone know why?

dax command using my date table:

EOM_DTBLE = 
CALCULATE(
    SUM('Table'[sales]),
    ENDOFMONTH('DATE'[Date])
)
