Filter by date periods

hi, MG25

You can use the measure below

measure = 
    CALCULATE(
        COUNTROWS('Table'),
            DATEDIFF('Table'[Product Date of Manufacture],
                'Table'[Product Return Date],
                DAY
        )<365
)

best regards.

I recommend you to create a date table in your model if you don't have one and create a relationship. Add the following measure and insert a Matrix visual.  I attached a sample file.

Less than one year = 
COUNTROWS(
    FILTER(
        Table5,
        INT( Table5[Product Return Date]  -  Table5[Product Date of Manufacture] ) < 365
    )
)
