Previous Year Calculations

[hsalasde]

Hello, 

I'm attempting to calculate Previous Year measures using SAMEPARIODLASTYEAR & by using Filsters. In both instances, the calculations are wrong. The data shows that the calculations made by Power BI are off by a day. The period for the current year is calculated from Sunday through Saturday. The Previous Year calculation is calculating from the previous Saturday through Friday. I've looked through board to find a solution, but I'm stumped. 

Here are my two different calculations which are giving the same result. 

Using DATESINPERIOD: 

PY Weekend Surg Mins w/ Filter =

CALCULATE(

    [Weekend Surg Mins],

    FILTER(

        DATESINPERIOD(

            'Date'[Date],

            DATEADD(

                LASTDATE('Date'[Date]),

                -1,

                YEAR

            ),

            -7,

            DAY

        ),

        WEEKDAY('Date'[Date], 1) IN {2,6,7,1}

    )

)

Using SAMEPERIODLASTYEAR:

PY Weekend Surg Mins =

CALCULATE(

    [Weekend Surg Mins],

    SAMEPERIODLASTYEAR('Date'[Date])

    )

Any help would be most appreciated!
