But i Found this answer by Joe Oppelt to Work Perfectly
Right click on the blue pill in the ROW shelf when you have MY(Date)
You have "More(MMMM YYY)" selected. Below that you will see another option for "Month (May 2015)".
Choose that. It will change the pill to green and change your viz, but don't worry.
Right click the green pill. Near the bollom you will see "Continuous" selected.
Click "Discrete" right above it. That changes the green pill to blue and puts your
viz back to the way you want it, and you have Month/Year seleted, but in a format that
allows you to change display formats to your liking.
