Hi @U156531 ,

Not sure how your data looks, if you can share some sample it will be helpful. 
If your scenario is that you have a date column and you want to compare it with the Previous month of current date then refer below DAX :

I tried this statement to get the previous month in "mmm" format .

 FORMAT(month(today())-1, "mmm") )

Unfortunatley it gives me Jan not May.
