$count is in a void context there. Either:
for ( my $count; $count < 7; $count++ ) {
Or:
for ( $count = 0; $count < 7; $count++ ) {
etc.
But it doesn't look like you are using $count inside the loop anyway so why
not just:
for ( 0 .. 6 ) {
And if you *really* need $count then:
for my $count ( 0 .. 6 ) {
if ($day == '01') {
You are using a numerical comparison on a string. Either:
if ( $day == 1 ) {
Or:
if ( $day eq '01' ) {
