Hello,
I have a Date table and I want to create a calculated column that gives me the date of the previous year. For example, if the date is 1/1/2018 the LY column should be 1/1/2017. Are there any DAX functions that will accomplish this? When I use SAMEPERIODLASTYEAR or DATEADD, it returns a table, so it won't work with a calculated column. Also, if there is a function, how would it handle the leap year? What would the previous year column look like for 2/29/2016?
Thanks.

HI @vega
Try this Column.
For 29 Feb 2016 it will give 1 Mar 2015
LY Date = DATE ( YEAR ( DateTable[Date] ) - 1, MONTH ( DateTable[Date] ), DAY ( DateTable[Date] ) )
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] ) ) )

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