    Hi vega,

     Based on my understanding, if this year is the leap year, the previous year column should display blank. For example the previous year of 2/29/2016 day is blank, because there is no 2/29/2015. Please create a calculated column using the formula.

    LY Date_Edit =
IF (
    MONTH ( DateTable[Date] ) = 2
        && DAY ( DateTable[Date] ) = 29,
    BLANK (),
    DATE ( YEAR ( DateTable[Date] ) - 1, MONTH ( DateTable[Date] ), DAY ( DateTable[Date] ) )
)


    Best Reards,

Hi Zubair_Muhammad,

This works very well as a calculated column. I was wondering if this can also be used as a measure?
