weeks_of_year starts with 1 in 2027

[markus-seidl]

If the function should iterate over all weeks in a year, than sometimes it should start with the week 53, for example in 2027.

I guess something like this?

 temp_first_of_year = date(self.year, 1, 1).isocalendar()[:2]

if temp_first_of_year[0] != self.year:
   # start with week 53

[markus-seidl]

I guess a year also sometimes ends with week "1" which is next year?

The documentation states that the first week of the year is the first week with at least 4 days in that year. For 2027 the first week starts on Monday 2027-01-04. There might be room for improvement in the documentation of it's not clear what weeks_of_year() it supposed to mean.
