DAX - DateDiff not working correctly

[JohnYetsko]

I'm using a DAX expression to compare a date column to todays date and enter a comment in a column based on the dfference.

However it appears that the DATEDIFF function is not working on dates after July 3rd 2024.

I can update the field to 7/3/2024 and it functions correctly, but entering 7/4/2024 it does not.

******

PlanCompliance =

IF(

ISBLANK('Plans-DR'[Expires]),

"No Plan Dates",

IF(

DATEDIFF('Plans-DR'[Expires], TODAY(), DAY) > 300,

"Non-Compliant",

"Compliant"

)

)

Try this DAX

PlanCompliance =
IF (
    ISBLANK ( 'Plans-DR'[Expires] ),
    "No Plan Dates",
    IF (
        'Plans-DR'[Expires] - TODAY() > 300,
        "Non-Compliant",
        "Compliant"
    )
)

Hello @JohnYetsko 

DATEDIFF('Plans-DR'[Expires], TODAY(), DAY)

This calculates the number of days from Expires to Today, which means:

If Expires = 07/03/2024 and Today = 04/30/2025, result = ~300 days

But if Expires = 07/04/2024, it's less than 300, so the IF logic flips

But — your logic might be reversed depending on which way you're counting.

If you're checking how many days left until the expiry date, you should flip the arguments in DATEDIFF:

PlanCompliance =

IF (

    ISBLANK('Plans-DR'[Expires]),

    "No Plan Dates",

    IF (

        DATEDIFF(TODAY(), 'Plans-DR'[Expires], DAY) > 300,

        "Non-Compliant",

        "Compliant"

    )

)

If this solved your issue, please mark it as the accepted solution. ✅

Are you trying to do this as a measure?  It works correctly as a calculated column
