Hi Stephen,
I was thinking about this last night. It seems that given the way Joda
time uses Periods, I should be able to use a Period to calculate a delta
between the first run date and the current date, then apply that delta in
months to the first run date, which creates the correct rolling start end
date. I've linked to the source here in case anyone wants to take a look at
how I did it. We use monthly rolling calculations based on when the user
signed up.
Months = created Date Time - current DateTime
New Range
created Date Time + Months
Here is the source I used
