MDX  - 12 trailing months

I need an MDX WHERE clause that will give me the selected date and the 11 preceding.  For example, select January 2014 and get Feb 2013 - Jan 2014.

Is there a DateDiff or something that I can use in the WHERE clause in MDX for this kind of query?

I have found LastPeriods:
WHERE (LastPeriods(12.0, [Dim Date.MonthNum].[11]))

But ... nothing there specifies the year.

Thanks!

OK, I think I have it:

WHERE (LastPeriods(366.0, [Dim Date.FullDate].[2013-11-30])

This seems to go back 366 days ... spanning the 12 months I want.
