You can clean it up and condense but the following should work ...

<dtml-let today="_.DateTime()">
<dtml-let cur_year="today.year()">
<dtml-let start_of_year="_.DateTime('01/01/'+_.str(cur_year))">
<dtml-let num_days="today-start_of_year">
<dtml-let week_number="_.int(num_days/7)">
   <dtml-var week_number>
</dtml-let>
</dtml-let>
</dtml-let>
</dtml-let>
</dtml-let>

Cheers,
Darran.
