I don't know if this qualifies as simple, but it seems to work: def addmonths(thedate,months): "Add <months> months to <thedate>." import datetime y,m,d = thedate.timetuple()[:3] y2, m2 = divmod(m+months-1, 12) return datetime.date(y+y2,m2+1,d) Note that the date constructor will raise an exception if the result happens to be an invalid date such as February 30th or November 31st. -Carsten -- http://mail.python.org/mailman/listinfo/python-list
