You did not specify what format your dates are in. But no matter, DateTime can handle most date/time functions. 
use strict;
use warnings;
use DateTime;
use DateTime::Span;
use Datetime::Format::ISO8601;

my $iso8601 = DateTime::Format::ISO8601->new;

while (<DATA>) {
    my ( $first, $last ) = split('\|');
    chomp $last;
    my $dt_set = DateTime::Span->from_datetimes(
        start  => $iso8601->parse_datetime($first),
        before => $iso8601->parse_datetime($last),
    );
    if ( $dt_set->contains( DateTime->now() ) ) {
        print "Within date range\n";
    }
    else {
        print "Not within date range\n";
    }
}
