well this is how I have done it, just out of interest, im going to need 
to build a few more date functions like this, how would I go about 
creating a plugin to include this?


            pLoopDate = Date.new(2005,10,1)
            pLoopDateMax = Date.new(2006, 10, 1)

            while pLoopDate <= pLoopDateMax
                pNumberOfMonths = pNumberOfMonths + 1
                if pLoopDate.month == 12
                    pLoopDate = Date.new((pLoopDate.year+1),1,1)
                else
                    pLoopDate = 
Date.new(pLoopDate.year,(pLoopDate.month+1),1)
                end
            end

You could do (date2.year*12+date2.month) - (date1.year*12+date1.month).

Use the date helper for this date diff issues,
ActionView::Helpers::DateHelper
