Which makes some sense considering a month can range from 28-31 days,
which would make the delta oddly fuzzy.
Here's one approach:
myDate = datetime.date.today()
newYear = myDate.year
newMonth = myDate.month + 3
if newMonth > 12:
newYear += 1
newMonth -= 12
inThreeMonths = datetime.date(newYear, newMonth, myDate.day)
#add extra analogous logic if you have to deal with February or 31st days.
Cheers,
Chris
