Rolling 12 month distinct count

I trying to create a data set which is distinct count of customers over a rolling 12 month period, which increments by a month but don't really know where to start so any help would be greatly appreciated.  What my desired output would look something like the table below.  Have attached a example input data set

@jboyle  one approach to solving this problem might involve summarize tools to perform the customer counts, and the generate rows tool with DateTime functions to create the data points required for your analysis:
