Yesterday last year DAX formula

[unclejemima]

For today I'm using 

Today= DATE(YEAR(NOW()),MONTH(NOW()), DAY(NOW())

How would I display Today last year?  I was thinking

TodayPrevYear = DATE(YEAR(NOW()-1),MONTH(NOW()), DAY(NOW())

But I get an error.

Can someone show me the correct formula to use for Today Last year?

Perhaps something like: 

Measure = DATE(YEAR(NOW())-1,MONTH(NOW()), DAY(NOW()-1))

You have to subtract 1 from the result of the YEAR function not inside the argument!

If you do YEAR ( NOW()-1 ) as you you've done you are basically asking for the function to return the YEAR of NOW()-1

which would be yesterday this year - thats why you have to get the year first and then subtract 1

TodayPrevYear = DATE ( YEAR ( NOW () ) - 1, MONTH ( NOW () ), DAY ( NOW () ) )

And same if you want yesterday previous year

Obviously for Day it won't matter if you subtract 1 inside or not

YesterdayPrevYear = DATE ( YEAR ( NOW () ) - 1, MONTH ( NOW () ), DAY ( NOW () ) - 1 )

 Hope this helps!

Hi, You can also obtain:

Today-inPreviousYear = EDATE(TODAY(),-12)

Yesterday-inPreviousYear = EDATE(TODAY(),-12)-1
