The WEEKDATXw.
format writes SAS date values in the form day-of-week, dd
month-name, yy (or yyyy):
dd
is an integer that
represents the day of the month.
yy or yyyy
is a two-digit or a
four-digit integer that represents the year.
If w is
too small to write the complete day of the week and month, then SAS
abbreviates as needed.
