I suspect there is no 'standard' definition of week number.
E.g. if the year begins on a Wednesday, is the following Monday part
of week 1 or week 2?
Once you decide, you can design a calculation starting with
"some_date_object.dayOfYear()" which will give you the day number in
the range 1 to 365 (or 366).
The simplest algorithm would be to say days 1-7 are week 1, 8-14
are week 2, etc. In that case
((some_date_object.dayOfYear() - 1) / 7) + 1
(or in dtml)
<dtml-var "((some_date_object.dayOfYear() - 1) / 7) + 1">
will compute a week number (in the range 1 to 53).
If your weeks must begin on Sundays, or Mondays, or whatever, you'll
have to first request the dow() from the first day of the relevant
year, and do a calculation based on how far into the week the first
calendar day of the year falls. If you want help with that,
describe the algorithm you want to use.
