I have a field in my shapefile that is of type "Date".I want to figure out the difference between that "Date" and today, in weeks.My assumption was that (datetime.date() - !Date!) would produce a timedelta object, which i would simply call to find out the difference. Hence my code below:(datetime.date.today() - !Date!).days / 7
Of course, that says it is a syntax error, which doesn't explain much. Any pointers to manipulating dates in the field calculator?
