Hi,
To add months with todays date, you can do it like this
from datetime import datetime
from dateutil.relativedelta import relativedelta
six_months_after  = datetime.now() + relativedelta(months=6) or in your code* change* the line ,
Date = datetime.datetime.now()  into
* *
*Date = datetime.now()*  For writing the values into field, you have to do like this
*self.* end_month = six_months_after
thanks
