I have a list of dates in the following format:

20061107
20100226
20110301
20110220
20100301
20061023
20110214
20090219
20110226
20110223

How can I do a check to see what dates are older than 90 days?

Thanks,

This should do it...
#!/usr/local/bin/perl

use strict;
use warnings;
use Date::Calc qw(:all);

my @today = Today();

# to read from STDIN, change <DATA> to <>
while (<DATA>) {
    chomp;
    die "invalid date: $_"
        unless (m{^(\d{4})(\d\d)(\d\d)$} and check_date($1, $2, $3));
    my @date = ($1, $2, $3);
    if (Delta_Days(@date, @today) > 90) {
        print $_, "\n";
    }
}
__DATA__
20061107
20100226
20110301
20110220
20100301
20061023
20110214
20090219
20110226
20110223
