You just need to:

1) Trim the first and last weeks off since they contain invalid dates.
2) Merge the overlapping last week of April and first week of May.
3) Count the resulting number of weeks in the list.

Alternatively, the dateutil.rrule module could probably be used to do
this fairly easily, but it's a third-party module and not part of the
standard library.
