If your date command don't support -d option, then use perl to calculate the passed date.
Code:
$ cat days_ago
days_ago()
{
perl -e '
# take 86400 * # of days from right now in epoch seconds
$yestertime = time - (86400 * $ARGV[0]);
$month = (localtime $yestertime)[4] + 1;
# day of the month
$day = (localtime $yestertime)[3];
# year
$year = (localtime $yestertime)[5] + 1900;
# US format mm dd yyyy
printf( "%4d%02d%02d", $year, $month, $day); ' $1
}
days_ago $1
