The YYMMDDw. format writes SAS date values in one of the
following forms:
yymmdd
<yy>yy–mm–dd
where
<yy>yy
is a two-digit or four-digit
integer that represents the year.
mm
is an integer that
represents the month.
dd
is an integer that
represents the day of the month.
To format a date that
has a four-digit year and no separators, use the YYMMDDx. format.
