I want to put a calculation into my system which is for billing.
I need to get it to work out from the start of the month then look 6 months ahead. For example I'd like it to show that the client will be billed from
1 October 2015 through 31 March 2016. I can't use days as obviously there are a differing amount of days in months and also it needs to show from start date to end date.
