after putting brkets around the entire match, it eliminated the problem of printing eveything else on the line, however it isnt printing the entire date match. 
$dir='C:/texts/';
opendir(directory,$dir) or die "cant";
while($file=readdir directory){
    next if $file=~/^\./;
    $rfname=$dir.$file;
# print "Found file: '$rfname'\n";
open (CONT, $rfname);
    while (<CONT>){
    if($_=~m/([0-3]?[0-9(th)?(st)?(nd)?(rd)?]\s+Jan(uary)?|Feb(ruary)?
+|Mar(ch)?|Apr(il)?|May|Jun(e)?|Jul(y)?|Aug(ust)?|Sep(tember)?|Oct(obe
+r)?|Nov(ember)?|Dec(ember)?\s+[0-9]?[0-9]?[0-9][0-9])/ig){
    print "$file\t $1\n";
    }
    elsif($_=~m/(Jan(uary)?|Feb(ruary)?|Mar(ch)?|Apr(il)?|May|Jun(e)?|
+Jul(y)?|Aug(ust)?|Sep(tember)?|Oct(ober)?|Nov(ember)?|Dec(ember)?\s+[

    print "$file\t $1\n";
    }
}
