The YYWEEKUw. format writes
a week-number format. The YYWEEKUw. format writes
the various formats depending on the specified width. Algorithm U calculates
the SAS date value by using the number of the week within the year (Sunday
is considered the first day of the week).
Refer to the following table for widths, formats, and examples:

The YYWEEKUw. format is similar
to the WEEKUw. format except that the YYWEEKUw. format does not specify the day-of-week information. Also,
the YYWEEKUw. format does not accept any width
that is greater than 8.
