I have a code as below. Moth May should be in Quarter 1 = QUARTER(TODAY()) but QUARTER('Calendar'[Date]) seems not producing the same output. is there a reason for that ? many thanks in advance.

 get_current_quarter = 

IF(
    AND(
    QUARTER(TODAY()) = QUARTER('Calendar'[Date]),
    YEAR(TODAY()) = YEAR('Calendar'[Date])
    ),
    "Yes",
    "No"
)
